Python Coding Challange - Question With Answer(01291224)

 

Step-by-Step Explanation

1. List Initialization:

   • my_list = [7, 2, 9, 4]
     This creates a list with the elements [7, 2, 9, 4] and assigns it to the variable my_list.

2. Using the .sort() Method:

   • my_list.sort() sorts the list in place, meaning it modifies the original list directly and does not return a new list.
   • The .sort() method returns None, which is a special Python value indicating that no meaningful value was returned.

   So, when you assign the result of my_list.sort() back to my_list, you are overwriting the original list with None.

3. Printing the Result:

   • print(my_list) will print None because the variable my_list now holds the return value of the .sort() method, which is None.
