Python Coding Challange - Question With Answer(01280125)

 

Explanation:

1. numbers = [1, 2, 3]
   • A list [1, 2, 3] is created and assigned to the variable numbers.
2. integers = numbers
   • The variable integers is assigned the same reference as numbers.
   • At this point, both integers and numbers refer to the same list in memory: [1, 2, 3].
3. numbers = numbers + [4, 5, 6]
   • The numbers + [4, 5, 6] creates a new list: [1, 2, 3, 4, 5, 6].
   • This new list is assigned back to the variable numbers.
   • Now, numbers refers to a new list [1, 2, 3, 4, 5, 6], but integers still refers to the original list [1, 2, 3] because it was not updated or modified.
4. print(integers)
   • The variable integers still refers to the original list [1, 2, 3], which remains unchanged.
   • So, the output is:

     
     [1, 2, 3]

---

Key Takeaway:

• The operation numbers = numbers + [4, 5, 6] creates a new list and reassigns it to numbers. It does not modify the original list numbers was referring to.
• If you want to modify the list in place, you can use numbers.extend([4, 5, 6]). In that case, integers would also reflect the changes since they share the same reference.

Python Coding Challange - Question With Answer(01270125)

 

Explanation

The first step in understanding what is going on in this wacky code is to take a look at what

 has to say about using return with yield:

return expr in a generator causes StopIteration(expr) to be raised upon exit from the generator.

In this case, StopIteration is raised at the beginning of my_func() due to the return statement

inside the function being called. Your code catches the StopIteration exception inside the list()

function at the end of the code.

Because an exception is raised, ["Python"] is not returned, so the list() function returns an empty

list.

If you’d like to get ["Python"] out of your code, you would need to modify the call to use the next()

function wrapped in an exception handler:

1 def my_func(value):

2 if value == 5:

3 return ["Python"]

4 else:

5 yield from range(value)

6

7 try:

8 next(my_func(5))

9 except StopIteration as exception:

10 print(f"StopIteration caught! {exception.value = }")

This code removes the call to list(), which will automatically catch the StopIteration exception

and uses the next() function instead. The next() function does not catch StopIteration, so you

wrap that call with Python’s try / except construct to catch that exception yourself.

To get the value of the exception, you can access the exception object’s value attribute.

Output : []

Python Coding challenge - Day 354| What is the output of the following Python Code?

 

Code

import time  

start = time.time()  

time.sleep(1)  

print(round(time.time() - start))

Explanation

1. Importing the time module

import time

The time module provides various functions to work with time in Python.

It includes features to measure the current time, calculate durations, and pause program execution.

2. Capturing the start time

start = time.time()

The time.time() function returns the current time in seconds as a floating-point number.

The number represents the Unix timestamp, which is the number of seconds since January 1, 1970 (known as the epoch).

This is used to record the starting point of the program execution.

3. Pausing the program for 1 second

time.sleep(1)

The time.sleep() function pauses the execution of the program for a specified amount of time, given in seconds.

Here, time.sleep(1) tells the program to wait for 1 second before proceeding to the next line.

4. Calculating the elapsed time

time.time() - start

The time.time() function is called again to get the current time (after the pause).

The difference between the current time and the recorded start time gives the elapsed time.

For example:

Start time: 1674821371.123

Current time: 1674821372.123

Elapsed time: 1674821372.123 - 1674821371.123 = 1.0

5. Rounding the elapsed time

round(time.time() - start)

The round() function rounds the result to the nearest integer.

Since the pause is for exactly 1 second, the elapsed time will be approximately 1.0, and rounding it gives 1.

6. Printing the result

print(round(time.time() - start))

This line prints the rounded elapsed time to the console.

Since the program pauses for 1 second, the output will be:

Final Output

1

Python Coding challenge - Day 353| What is the output of the following Python Code?

 

Code

import json  

data = '{"x": 10, "y": 20}'  

print(json.loads(data)["y"])

Explanation

1. Importing the json module

import json

The json module is part of Python's standard library.

It allows you to work with JSON data (JavaScript Object Notation), a lightweight data-interchange format used for storing and exchanging data.

JSON data is commonly used in APIs, web applications, and configuration files.

2. Creating a JSON-formatted string

data = '{"x": 10, "y": 20}'

data is a JSON-formatted string.

A JSON string always uses double quotes for keys and string values.

Here, the string represents a dictionary-like structure with two key-value pairs:

{

  "x": 10,

  "y": 20

}

3. Converting the JSON string into a Python dictionary

json.loads(data)

The json.loads() function converts the JSON string into a Python dictionary.

After this operation, the result is:

{"x": 10, "y": 20}

x becomes a key with the value 10.

y becomes a key with the value 20.

This makes it easy to access and manipulate the data as if it were a normal Python dictionary.

4. Accessing the value associated with the key "y"

json.loads(data)["y"]

The key "y" is used to retrieve its corresponding value from the dictionary.

From the converted dictionary:

{"x": 10, "y": 20}

The value associated with "y" is 20.

5. Printing the value

print(json.loads(data)["y"])

The print() function outputs the value 20 to the console.

Final Output

20

Python Coding challenge - Day 352| What is the output of the following Python Code?

 

Code Explanation:

1. Importing the deque class

from collections import deque

We import deque from the collections module.

Think of a deque like a special list, but it is optimized for fast addition and removal of elements at both the beginning and the end.

2. Creating a deque

d = deque([1, 2, 3])

Here, we create a deque named d and initialize it with the list [1, 2, 3].

At this point, the deque contains these elements: 1, 2, 3.

Imagine the deque as a row of blocks where you can easily add or remove items from either side:

[1, 2, 3]

3. Adding an element to the front

d.appendleft(0)

The appendleft() method is used to add the element 0 to the left side of the deque.

After this operation, the deque becomes:

[0, 1, 2, 3]

This is different from a regular list where inserting an element at the beginning (list.insert(0, value)) is slower because it shifts all other elements. With deque, it’s fast and efficient.

4. Printing the deque

print(d)

This prints the entire deque, showing its contents in the following format:

deque([0, 1, 2, 3])

Visualizing the Operations

[1, 2, 3]

Use appendleft(0):

[0, 1, 2, 3]

Final Output

When you run the code, the output will be:

deque([0, 1, 2, 3])
