for i in vary(3):
go
print(i)
a) 0 1 2
b) 1 2 3
c) 2 1 0
d) 3 2 1 0
Reply: c
Rationalization: The loop iterates over the numbers from 0 to 2, however the go assertion contained in the loop does nothing, so the worth of i stays 2 when printed outdoors the loop.
Q28. What’s the function of the go assertion in Python?
a) To exit from a loop prematurely
b) To skip the present iteration of a loop
c) To execute a block of code if a situation is fake
d) To do nothing and act as a placeholder
Reply: d
Rationalization: The go assertion does nothing and acts as a placeholder the place syntactically an announcement is required however no motion is desired or wanted.
Q29. What’s the function of the else block in a loop in Python?
a) To execute if the loop encounters an error
b) To execute if the loop completes with out encountering a break assertion
c) To execute if the loop encounters a proceed assertion
d) To execute if the loop encounters a go assertion
Reply: b
Rationalization: The else block in a loop executes when the loop completes usually, which means it doesn’t encounter a break assertion.
Q30. What’s the output of the next code?
x = 10
if x > 5:
print("Hiya")
elif x > 8:
print("Hello")
else:
print("Hey")
a) Hey
b) Hello
c) Hiya
d) Hiya, Hello
Reply: c
Rationalization: The situation x > 5 is true as a result of x is 10, so the corresponding code block is executed, printing “Hiya”. Despite the fact that x > 8 can also be true, the elif block is skipped as a result of the if situation was already met.
Q31. What’s the output of the next code?
for i in vary(1, 6):
if i % 2 == 0:
print(i)
proceed
print("*")

c) n2nn*n4n
d) nn2n*n4n
Reply: b
Rationalization: On this code, for every quantity i from 1 to five, if i is even, it’s printed, and the loop continues to the subsequent iteration utilizing proceed. If i is odd, “*” is printed as a substitute.
Q32. What would be the output of the next code?
x = 5
whereas x > 0:
print(x)
x -= 1
else:
print("Carried out")
a) 5n4n3n2n1nDone
b) Donen5n4n3n2n1
c) 5n4n3n2n1
