num = [10, 20, 30, 40, 50] num[2:4] = [ ] print(num)

Code :num = [10, 20, 30, 40, 50]num[2:4] = [ ]print(num)Solution and Explanation : In the provided code, you have a list num containing the elements [10, 20, 30, 40, 50]. Then, you use slicing to modify elements from index 2 to 3 (not including 4) by assigning an empty list [] to that slice. Let's break down the code step by step:num = [10, 20,...

a = [1, 2, 3, 4] b = [1, 2, 5] print(a < b)

 In Python, when comparing lists using the less than (<) operator, the lexicographical (dictionary) order is considered. The comparison is performed element-wise until a difference is found. In your example:a = [1, 2, 3, 4]b = [1, 2, 5]print(a < b)The comparison starts with the first elements: 1 in a and 1 in b. Since they are equal, the...

So, it produces the numbers 0, 1, 2, 3, and 4.b. range(1, 10, 3) - This generates a sequence of integers starting...

Can a do-while loop be used to repeat a set of statements in Python?

 Python does not have a built-in "do-while" loop like some other programming languages do. However, you can achieve similar behavior using a "while" loop with a break statement.Here's an example of how you can simulate a "do-while" loop in Python:while True:    # Code block to be repeated    # Ask the user if they want to repeat...

Can a while/for loop be used in an if/else and vice versa in Python?

 Yes, it is entirely valid to use loops within conditional statements (if/else) and vice versa in Python. You can nest loops inside if/else statements and if/else statements inside loops based on the requirements of your program.Here's an example of a while loop inside an if/else statement:x = 5if x > 0:    while x > 0:   ...

Can a while loop be nested within a for loop and vice versa?

Yes, both while loops can be nested within for loops and vice versa in Python. Nesting loops means placing one loop inside another. This is a common programming practice when you need to iterate over elements in a nested structure, such as a list of lists or a matrix.Here's an example of a while loop nested within a for loop:for i in range(3): ...

Can range( ) function be used to generate numbers from 0.1 to 1.0 in steps of 0.1?

 No, the range() function in Python cannot be used directly to generate numbers with non-integer steps. The range() function is designed for generating sequences of integers.However, you can achieve the desired result using the numpy library, which provides the arange() function to generate sequences of numbers with non-integer steps. Here's an...

Code - a = 10b = 60if a and b > 20 :  print('Hello')else :  print('Hi')Explanation -The above code checks the condition a and b > 20. In Python, the and operator has a higher precedence than the comparison (>), so the expression is evaluated as (a) and (b > 20).Here's how it breaks down:The value of a is 10.The value of b...

a = 10 a = not not a print(a)

CODE - a = 10a = not not aprint(a)Solution - In the above code, the variable a is initially assigned the value 10. Then, the line a = not not a is used. The not operator in Python is a logical NOT, which negates the truth value of a boolean expression.In this case, not a would be equivalent to not 10, and since 10 is considered "truthy" in...
