Which of the following loops is used for definite iteration?

• a) while loop

• b) for loop

• c) repeat loop

• d) if loop

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

• "for" loops can have a condition, while "while" loops cannot.

• "while" loops are used for counting, while "for" loops are used for indefinite iterations.

• "for" loops can only iterate over lists, while "while" loops can iterate over any data type.

• "for" loops specify the iteration variable explicitly, while "while" loops do not.

What will be the output of the following code?

x = 5

while x > 0:

print(x)

x -= 1

else:

print("Loop finished.")

• 5 4 3 2 1

• 5 4 3 2 1 Loop finished.

• 1 2 3 4 5

• Loop finished.

What is the output of the following code?

for i in range(1,6+1):

print(i)

• 1234567

• 1234567+1

• 7654321+1

• 123456

How can you prevent an infinite loop in Python?

• By using the "break" statement.

• By ensuring the loop condition becomes False at some point.

• By using the "continue" statement.

• By using the "pass" statement.

x = 5

while x > 0:

x -= 1

print(x)

What will be the output of the code snippet above?

• 5

• 4

• 1

• 0

Which of the following code snippets will correctly print all the even numbers from 2 to 10 using a loop in Python?

• for i in range(2, 11):

  if i % 2 == 0:

  print(i)

• num = 2

  while num <= 10:

  if num % 2 == 0:

  print(num)

  num += 2

• for i in range(2, 11, 2):

  print(i)

• num = 2

  while num < 10:

  if num % 2 == 0:

  print(num)

  num += 1

Which loop construct in Python is best suited for iterating through a known sequence, such as a list or a range of numbers?

• if-else loop

• while loop

• for loop

• do-while loop

Which statement is used to skip the rest of the current iteration and continue to the next iteration in a loop?

• skip

• next

• continue

• break

What is the purpose of the "range()" function in a "for" loop in Python?

• To create an empty sequence

• To generate a list of numbers for iteration

• To check the condition for the loop

• To define the loop counter
