Python Loops and Control Statements Quiz9a

What is the primary purpose of using loops in Python?

• To automate repetitive tasks
• To create complex data structures
• To manage memory allocation
• To handle exceptions

Which of the following correctly describes a 'for' loop in Python?

• It executes a block of code while a condition is true
• It iterates over a sequence of items
• It is used for error handling
• It can only iterate through lists

What will be the output of the following code? for i in range(3): print(i)

• 0 1 2
• 1 2 3
• 0 1 2 3
• 3 2 1

In a 'while' loop, when is the condition checked?

• Before each iteration
• After each iteration
• Only once at the beginning
• Only when an error occurs

What does the 'break' statement do in a loop?

• It skips the current iteration
• It terminates the loop immediately
• It pauses the loop for a specified time
• It continues to the next iteration

Which of the following is NOT a valid use of the 'continue' statement?

• To skip the current iteration
• To exit the loop
• To move to the next iteration
• To ignore certain conditions

What is the output of the following code? for i in range(2, 10, 2): print(i)

• 2 4 6 8
• 2 3 4 5 6 7 8 9
• 2 4 6 8 10
• 0 2 4 6 8

How does the 'pass' statement function in Python?

• It terminates the loop
• It acts as a placeholder
• It skips the current iteration
• It raises an error

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

• For loops are used for fixed iterations, while while loops are used for conditions
• For loops can only iterate through lists, while while loops can iterate through any data type
• For loops require a condition, while while loops do not
• For loops are faster than while loops

Which of the following statements about the range() function is true?

• It can only take one argument
• It generates a sequence of numbers
• It can only generate even numbers
• It is used to create lists
