fruits = ["apple", "banana", "cherry"]
for fruit in fruits:
print(fruit)
a) apple banana cherry
b) [“apple”, “banana”, “cherry”]
c) 0 1 2
d) No output
Reply: a
Rationalization: The for
loop iterates over every aspect within the fruits
checklist and prints every aspect individually.

b) To iterate over gadgets in a sequence
c) To outline a operate
d) To execute a block of code repeatedly till a situation is fake
Reply: a
Rationalization: The vary() operate generates a sequence of numbers usable for iteration, as indices, or any goal requiring a sequence of numbers.
Q16. What’s going to the next code snippet print?
for i in vary(3):
print(i)
a) 0 1 2
b) 1 2 3
c) 2 1 0
d) 3 2 1 0
Reply: a
Rationalization: The vary(3)
operate generates numbers from 0 to 2 (inclusive), so the loop will print every quantity in that vary.
Q17. What would be the output of the next code?
for i in vary(1, 6):
if i == 3:
proceed
print(i)
a) 1 2
b) 1 2 3
c) 1 2 4 5
d) 1 2 4
Reply: c
Rationalization: The proceed
assertion skips the remainder of the loop and strikes to the following iteration. So when i
equals 3, it skips printing that worth.
Q18. What would be the output of the next code?
for i in vary(3):
for j in vary(3):
print(i + j, finish=' ')
print()
a) 0 1 2
1 2 3
2 3 4
b) 0 1 2
1 2 3
2 3 4

1 2 3
2 3 4
4 5 6
d) 0 1 2
2 3 4
4 5 6
Reply: a
Rationalization: The outer loop iterates thrice, and for every iteration of the outer loop, the interior loop additionally iterates thrice. The values of i
and j
are added collectively and printed. Every iteration of the outer loop begins a brand new line.
Q19. What will likely be printed by the next code?
num = 5
whereas num > 0:
print(num)
num -= 1
if num == 3:
break
else:
print("Executed")
a) 5 4 3 2 1
b) 5 4
c) Executed
d) 5 4 3
Reply: b
Rationalization: The whereas
loop iterates so long as num
is bigger than 0. Contained in the loop, num
is decremented by 1 in every iteration. When num
turns into 3, the break
assertion is encountered, and the loop terminates.
Q20. What’s the output of the next code?
x = 10
if x > 5:
print("A")
elif x > 7:
print("B")
else:
print("C")
a) A
b) B
c) C
d) A and B
Reply: a
Rationalization: The situation x > 5
evaluates to True since x
is 10. Due to this fact, the code contained in the if
block executes, printing “A”.
Q21. What would be the output of the next code?
x = 5
whereas x > 0:
print(x, finish=" ")
x -= 2
if x == 1:
break
else:
print("Executed")
a) 5 3 1
b) 5 3
c) 5 3 Executed
d) 5 3 1 Executed
Reply: a
Rationalization: The whereas
loop iterates till x
turns into 1. Contained in the loop, x
is decremented by 2 in every iteration. When x
turns into 1, the loop breaks, and the else
block shouldn’t be executed.
Q22. What’s the output of the next code?
for i in vary(5):
if i == 2:
proceed
print(i, finish=" ")
a) 0 1 3 4
b) 0 1 2 3 4
c) 0 1 3 4 5
d) 0 1 2 3 4 5
Reply: a
Rationalization: The proceed
assertion skips the present iteration when i
equals 2. Due to this fact, 2 shouldn’t be printed.
Q23. What’s the output of the next code?
num = 0
whereas num < 5:
print(num)
num += 1
else:
print("Loop accomplished.")
a) 0 1 2 3 4
b) 0 1 2 3 4 Loop accomplished.
c) Loop accomplished.
d) This code will lead to an error.
Reply: b
Rationalization: The whereas
loop iterates till num
is lower than 5, printing the worth of num
in every iteration. As soon as num
turns into 5, the loop terminates, and the else
block is executed.
Q24. What would be the output of the next code?
x = 10
if x > 5:
print("Larger than 5")
if x > 8:
print("Larger than 8")
if x > 12:
print("Larger than 12")
else:
print("Equal or lower than 12")
a) Larger than 5
Larger than 8
Equal or lower than 12
b) Larger than 5
Larger than 8
Larger than 12
Equal or lower than 12
c) Larger than 5
Larger than 8
d) Equal or lower than 12
Reply: a
Rationalization: Every if
assertion is unbiased of the others, so all situations which can be true will execute their corresponding print
statements.
Q25. What would be the output of the next code?
for i in vary(3):
for j in vary(3):
print(i * j, finish=' ')
print()
a) 0 0 0
0 1 2
0 2 4
b) 0 1 2
0 2 4
0 3 6
c) 0 0 0
0 1 2
0 2 4
0 3 6
d) 0 0 0
0 1 2
0 1 2
Reply: a
Rationalization: The code makes use of nested loops to iterate over every mixture of i
and j
, printing their product. The print()
operate with no arguments prints a newline, separating every row.
Q26. What would be the output of the next code?
num = 10
whereas num > 0:
print(num)
num -= 3
else:
print("Loop accomplished.")
a) 10 7 4 1 Loop accomplished.
b) 10 7 4 1
c) Loop accomplished.
d) This code will lead to an error.
Reply: a
Rationalization: The whereas
loop decrements num
by 3 in every iteration till num
turns into 0. As soon as num
turns into 0, the loop terminates, and the else
block is executed.
Q27. What’s going to the next code snippet print?
for i in vary(3):
cross
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 cross
assertion contained in the loop does nothing, so the worth of i
stays 2 when printed exterior the loop.
Q28. What’s the goal of the cross
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 cross
assertion does nothing and acts as a placeholder the place syntactically a press release is required however no motion is desired or wanted.
Q29. What’s the goal 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 cross 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”. Although x > 8
can 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("*")
a) n2nn4n*
b) n2nn4n*n
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 following 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("Executed")
a) 5n4n3n2n1nDone
b) Donen5n4n3n2n1
c) 5n4n3n2n1
d) Executed
Reply: a
Rationalization: The whereas
loop prints the values of x
from 5 to 1, then after x
turns into 0, the else
block is executed, printing “Executed”.
Q33. What would be the output of the next code?
for i in vary(1, 6):
if i == 3:
break
print(i)
else:
print("Loop accomplished.")
a) 1n2
b) 1n2n3n4n5nLoop accomplished.
c) 1n2n3n4n5
d) 1n2n3
Reply: a
Rationalization: The loop breaks when i
equals 3, so the else
block shouldn’t be executed.
