Understanding Loops in Python

What is the output of the following Python code snippet? ```python for i in range(1, 5): print(i) ```

• 1, 2, 3, 4, 5

• 1, 2, 3, 4

• 0, 1, 2, 3, 4

• 0, 1, 2, 3

Consider the following Python code: ```python count = 0 name = "Eleanor" for letter in name: if letter == "e": count += 1 print(count) ``` What will be the output of this code?

• 0

• 1

• 2

• 3

Which of the following statements about while loops is true?

• A while loop always executes at least once.

• A while loop is always count-controlled.

• A while loop can be both count-controlled and condition-controlled.

• A while loop is the same as a for loop.

What is the main difference between a for loop and a while loop in Python?

• A for loop is used for condition-controlled loops, while a while loop is used for count-controlled loops.

• A for loop is used for count-controlled loops, while a while loop is used for condition-controlled loops.

• A for loop can only iterate over lists, while a while loop can iterate over any data structure.

• A for loop can only be used with numbers, while a while loop can be used with strings.

In the context of recursion, what is a base case?

• The case where the function calls itself indefinitely.

• The condition under which the recursive function stops calling itself.

• The first call to the recursive function.

• The last call to the recursive function.
