Python Day - 3

What is the purpose of a loop in Python?

• To define functions

• To repeatedly execute a block of code

• To store data values

• To print messages

Which type of loop is used to iterate over a sequence in Python?

• While loop

• If loop

• For loop

• Repeat loop

In a "for" loop, what does the variable after "for" represent?

• The condition

• The iteration variable

• The sequence to be looped

• The loop counter

What is the output of the following "for" loop:
numbers = [1, 2, 3, 4]

for num in numbers:

print(num * 2)

• 1 2 3 4

• 2 4 6 8

• 1 4 9 16

• 2 3 4 5

What statement is used to exit a "for" loop prematurely in Python?

• exit

• terminate

• stop

• break

"predict the output"

for i in range (1 , 6 , 2):

  print(i)

• 1 2 3

• 1 3 5

• 2 4 5

• 1 3 6

What is the output of the following "for" loop:

a  = [1 , 2 , 3, 5, 7]

for i in a:

  if i == 3:

    continue

  print(i)

• 0 1 2 3

• 2 3 4 6

• 1 2 3 4

• 1 2 5 7

Which loop is more appropriate when you want to iterate a specific number of times known in advance?

• While loop

• Until loop

• Repeat loop

• For loop

What is the output of the following "for" loop:

name = "hello"

for i in name:

  print(i,end = "@")

• @hello@

• h e l l o

• hello

• h@e@l@l@o

What is the output of the following code:

for i in range(1,10,2): 

if i==5:

    continue

  print(i)

• 2 4 6 8

• 1 4 7 8

• 1 2 4 6

• 1 3 7 9
