How much do you know about list in Python?

1. Which value is used to represent the first index of

list?

(a) 1 (b) 0

(c) −1 (d) a

Ans. (b) To access the list’s elements, index number is used. The

index number should be an integer. Index of 0 refers to first

element, 1 refers to second element and so on.

2. Choose the output of following Python code.

1= list ()

print ( 1)

(a) [] (b) ()

(c) [,] (d) Empty

Ans. (a) Empty list can be created in Python using []. To create

empty list, list () is also used.

3. Suppose list

1= [10, 20, 30, 40, 50, 60, 70]

print( 1[−3])

(a) 30 (b) 50

(c) 40 (d) Error

Ans. (b) The index of −1 refers to the last element, −2 refers to the

second last element and so on. Hence, −3 refers to third last

element, i.e. 50.

4. Choose the output from following code.

list1 = [‘A’, ‘R’, ‘I’,‘H’,‘A’,‘N’,‘T’]

print (list1 [7])

(a) T (b) N

(c) A (d) Error

Ans. (d) In the given code, we are trying to access 8th element

from the list which does not exist as we are having total 7

elements for which the last index is 6. So, Python will give

an IndexError.

5. Which function is used to insert an element at

specified position in the list?

(a) extend () (b) append ()

(c) insert () (d) add ()

Ans. (c) insert () function is used to insert an element at specified

position in the list. This method takes two arguments : one

for index number and second for element value.

Syntax list_name.insert(index, element)

6. Choose the correct option for the following.

l1 = [2, 5, 7]

l = l1+ 5

print (l)

(a) [7, 10, 12]

(b) [2, 5, 7, 5]

(c) [5, 2, 5, 7]

(d) TypeError

Ans. (d) + operator cannot add list with other type as number or

string because this operator is used only with list types.

So, it will give TypeError as it can only concatenate list (not

“int”) to list.

7. What is the output of following code?

l1 = [3, 2, 6]

l = l1 * 2

print (l)

(a) [3, 2, 6, 3, 2, 6]

(b) [6, 4, 12]

(c) [3, 4, 12]

(d) TypeError

Ans. (a) * operator can repeat the elements of the list.

Syntax list = list1 * digit

8. Which of the following is true regarding lists in

Python?

(a) Lists are immutable.

(b) Size of the lists must be specified before its initialisation.

(c) Elements of lists are stored in contiguous memory

location.

(d) size(list1) command is used to find the size of lists.

Ans. (c) Elements of lists are stored in contiguous memory

location, so it is true regarding lists in Python.

9. Suppose list1 is [56, 89, 75, 65, 99], what is the

output of list1 [− 2]?

(a) Error (b) 75

(c) 99 (d) 65

Ans. (d) −1 corresponds to the last index in the list, −2 represents

the second last element and so on.

So, the output for list1 [− 2] is 65 because 65 is second last

element of list1.

10. Identify the output of following code.

List1=[1, 2, 3, 7, 9]

L=List1.pop(9)

print(L)

(a) Syntax error (b) 9

(c) [1, 2, 3, 7] (d) None of these

Ans. (a) In pop(9), parentheses put index number instead of

element. In the given list, maximum index number is 4, then

9 is out of index range.

11. Suppose list1 is [2445,133,12454,123], what is the

output of max(list1)?

(a) 2445 (b) 133

(c) 12454 (d)123

Ans. (c) max() returns the maximum element in the list. From

given options, 12454 is the element with maximum value.

12. To add a new element to a list, which command will

we use?

(a) list1.add(8)

(b) list1.append(8)

(c) list1.addLast(8)

(d) list1.addEnd(8)

Ans. (b) We use the function append() to add an element to the list.

13. What will be the output of the following Python

code?

list1=[9, 5, 3, 5, 4]

list1[1:2]=[7,8]

print(list1)

(a) [9,5, 3, 7, 8] (b) [9, 7, 8, 3, 5, 4]

(c) [9,[ 7, 8], 3, 5,4] (d) Error

Ans. (b) In the piece of code, slice assignment has been

implemented. The sliced list is replaced by the assigned

elements in the list.

14. Consider the declaration a=[2, 3, ‘Hello’, 23.0].

Which of the following represents the data type of

‘a’?

(a) String (b) Tuple

(c) Dictionary (d) List

Ans. (d) List contains a sequence of heterogeneous elements

which store integer, string as well as object. It can created to

put elements separated by comma (,) in square brackets [].

15. Identify the output of the following Python

statement.

x=[[1, 2, 3, 4], [5, 6, 7, 8]]

y=x [0] [2]

print(y)

(a) 3 (b) 4

(c) 6 (d) 7

Ans. (a) x is a list, which has two sub-lists in it. Elements of first

list will be represented by [0] [i] and elements of second list

will be represented by [1] [i].

16. Which method will empty the entire list?

(a) pop() (b) clear()

(c) sort() (d) remove()

Ans. (b) clear() method is used to remove all the items of a list.

This method will empty the entire list.

Syntax

list_name.clear()

17. Which of the following allows us to sort the list

elements in descending order?

(a) reverse = True

(b) reverse = False

(c) sort (descending)

(d) sort. descending

Ans. (a) sort() is used to sort the given list in ascending order. The

sort() has an argument called reverse = True. This allows us

to sort the list elements in descending order.

18. Identify the correct output.

>>>l1 = [34, 65, 23, 98]

What is the output of following Python code?

 What is the output of following Python code?

a =[[0, 1, 2], [3, 4, 5, 6]]

b =a[1] [2]

print (b)

Answer with Explanation:

Let's break down your code step by step:

a = [[0, 1, 2], [3, 4, 5, 6]]

Here, you have defined a list a that contains two sub-lists. The first sub-list is [0, 1, 2], and the second sub-list is [3, 4, 5, 6]. So, a is a list of lists.

b = a[1][2]

This line of code is accessing elements in the nested list. Let's break it down:

a[1] accesses the second sub-list in a. In Python, indexing starts from 0, so a[1] refers to [3, 4, 5, 6].

[2] then accesses the third element in this sub-list. Again, indexing starts from 0, so a[1][2] refers to the element at index 2 in the sub-list [3, 4, 5, 6].

As a result, b is assigned the value 5, which is the third element in the second sub-list.

print(b)

Finally, the print(b) statement outputs the value of b, which is 5, to the console.

So, when you run this code, the output will be:

5

This is because b contains the value at index [1][2] in the nested list a, which is 5.

Python Coding challenge - Day 114 | What is the output of the following Python Code?

 

Code: 

def fun(num):

    if num > 10:

        return num - 10

    return fun(fun(num + 11))

print(fun(5))

Solution and Explanantion: 

The output of the code is 1.

Here's a breakdown of how the code works:

Function Definition:

The code defines a recursive function named fun that takes a single argument, num.

Base Case:

The if statement checks if num is greater than 10. If it is, the function returns num - 10. This is the base case that stops the recursion.

Recursive Calls:

If num is not greater than 10, the function calls itself twice, creating two recursive calls:

fun(fun(num + 11))

The inner call fun(num + 11) adds 11 to num and passes the result to the fun function again.

The outer call takes the result of the inner call and passes it to the fun function once more.

Execution Flow:

When you call fun(5), here's what happens:

5 is not greater than 10, so the function calls fun(fun(16)).

The inner call fun(16) now executes. 16 is greater than 10, so the base case triggers and returns 16 - 10 = 6.

The outer call now has 6 as its argument. 6 is not greater than 10, so it calls fun(fun(17)).

The inner call fun(17) executes. 17 is greater than 10, so the base case returns 17 - 10 = 7.

The outer call now has 7 as its argument. 7 is not greater than 10, so it calls fun(fun(18)).

This process continues until fun(25) is reached. At this point, the base case returns 25 - 10 = 15.

The values start propagating back through the recursive calls, eventually leading to the final return value of 1.

Key Points:

The code demonstrates recursion, where a function calls itself within its own definition.

The base case is crucial to prevent infinite recursion and ensure the function eventually terminates.

Recursive functions can be helpful for solving problems that can be broken down into smaller, self-similar subproblems.

Which of the following are valid return statements?

 

Which of the following are valid return statements?

return (a, b, c)

return a + b + c

return a, b, c

All three of the provided return statements are valid in Python, but they have different implications:

return (a, b, c): This returns a single tuple containing the values of a, b, and c. For example, if a = 1, b = 2, and c = 3, the function would return the tuple (1, 2, 3).

return a + b + c: This returns the sum of a, b, and c. If a = 1, b = 2, and c = 3, the function would return the value 6.

return a, b, c: This returns a tuple containing the values of a, b, and c. This is a more concise way of expressing the first option. For the same example values, it would return the tuple (1, 2, 3).

Choose the one that fits your specific use case and the desired return value format in your function.

Python Coding challenge - Day 113 | What is the output of the following Python Code?

 

The code you provided is attempting to generate a Fibonacci sequence and append the values to the list lst. However, it seems like there's a small mistake in your code. The range in the list comprehension should go up to 4, not 5, to generate the Fibonacci sequence up to the 4th element. Here's the corrected code:

lst = [0, 1]

[lst.append(lst[k - 1] + lst[k - 2]) for k in range(2, 5)]

print(lst)

After running this code, lst will be:

[0, 1, 1, 2, 3]

This list represents the Fibonacci sequence up to the 4th element. The initial list [0, 1] is extended by three more elements generated by adding the last two elements of the list to get the next one.

How to write program that generates a list of integer coordinates for all points in the first quadrant from (1, 1) to (5, 5) using list comprehension?

 

You can use list comprehension to generate a list of integer coordinates for all points in the first quadrant from (1, 1) to (5, 5). Here's an example in Python:

coordinates = [(x, y) for x in range(1, 6) for y in range(1, 6)]

print(coordinates)

This code will produce a list of tuples where each tuple represents a coordinate in the first quadrant, ranging from (1, 1) to (5, 5). The range(1, 6) is used to include values from 1 to 5 (inclusive) for both x and y.

After running this code, coordinates will contain the following list:

[(1, 1), (1, 2), (1, 3), (1, 4), (1, 5),  (2, 1), (2, 2), (2, 3), (2, 4), (2, 5),  (3, 1), (3, 2), (3, 3), (3, 4), (3, 5),  (4, 1), (4, 2), (4, 3), (4, 4), (4, 5),  (5, 1), (5, 2), (5, 3), (5, 4), (5, 5)]

Python Coding challenge - Day 112 | What is the output of the following Python Code?

 

Code :

x = 15

y = 10

result = x if x < y else y

print(result)

Solution and Explanation: 

Let's break down the code step by step:

Variable Initialization:

x = 15

y = 10

Two variables, x and y, are initialized with the values 15 and 10, respectively.

Conditional Expression:

result = x if x < y else y

This line uses a conditional expression. The syntax is a if condition else b, meaning if the condition is true, the value of a is assigned to the variable; otherwise, the value of b is assigned. In this case, it's checking whether x is less than y. If it is true, result will be assigned the value of x, otherwise, it will be assigned the value of y.

Printing the Result:

print(result)

Finally, the code prints the value of result.

Execution:

In this specific example, x (15) is not less than y (10). Therefore, the conditional expression evaluates to y, and the value 10 is assigned to result. The print(result) statement then outputs 10 to the console.

In summary, the code compares the values of x and y and assigns the smaller value to the variable result, which is then printed. In this particular case, the output will be 10 because y is smaller than x.

Python Coding challenge - Day 111 | What is the output of the following Python Code?

 

Code : 

complex_num = 4 + 3j

print(abs(complex_num))

Solution and Explanantion:

The above code calculates the absolute value (magnitude) of a complex number and prints the result. In this case, the complex number is 4 + 3j. The absolute value of a complex number is given by the square root of the sum of the squares of its real and imaginary parts.

Let's break it down:

complex_num = 4 + 3j

This line creates a complex number with a real part of 4 and an imaginary part of 3.

print(abs(complex_num))

This line calculates the absolute value of the complex number using the abs function and then prints the result. The output will be:

5.0

So, the absolute value of the complex number 4 + 3j is 5.0.

Difference between Lists and sets in Python

 Lists and sets in Python are both used for storing collections of elements, but they have several differences based on their characteristics and use cases. Here are some key differences between lists and sets in Python:

Ordering:

Lists: Maintain the order of elements. The order in which elements are added is preserved, and you can access elements by their index.

Sets: Do not maintain any specific order. The elements are unordered, and you cannot access them by index.

Uniqueness:

Lists: Allow duplicate elements. You can have the same value multiple times in a list.

Sets: Enforce uniqueness. Each element in a set must be unique; duplicates are automatically removed.

Declaration:

Lists: Created using square brackets [].

Sets: Created using curly braces {} or the set() constructor.

Mutability:

Lists: Mutable, meaning you can change the elements after the list is created. You can add, remove, or modify elements.

Sets: Mutable, but individual elements cannot be modified once the set is created. You can add and remove elements, but you can't change them.

Indexing:

Lists: Allow indexing and slicing. You can access elements by their position in the list.

Sets: Do not support indexing or slicing. Elements cannot be accessed by position.

Here's a brief example illustrating some of these differences:

# Lists

my_list = [1, 2, 3, 3, 4, 5]

print(my_list)        # Output: [1, 2, 3, 3, 4, 5]

print(my_list[2])     # Output: 3

# Sets

my_set = {1, 2, 3, 3, 4, 5}

print(my_set)         # Output: {1, 2, 3, 4, 5}

# print(my_set[2])    # Raises TypeError, sets do not support indexing

In the above example, the list allows duplicates and supports indexing, while the set automatically removes duplicates and does not support indexing. Choose between lists and sets based on your specific requirements for ordering, uniqueness, and mutability.

Python Coding challenge - Day 110 | What is the output of the following Python Code?

 

aList = ["Clcoding", [4, 8, 12, 16]]   

print(aList[1][3])

Solution and Explanation:

The given code is a Python script that defines a list called aList containing two elements: the string "Clcoding" and another list [4, 8, 12, 16]. The script then prints the value at the index 3 of the second element (the inner list) of aList.

Let's break it down:

aList[1] refers to the second element of aList, which is [4, 8, 12, 16].

aList[1][3] accesses the element at index 3 of the inner list, which is 16.

Therefore, the output of the code will be:

16
