Output of pass in a loop

What is the output of this code snippet?

Python

for i in range(3):
    pass
print('Done')

A SyntaxError

B 0 1 2

C Done

D None

💡 Hint

The pass statement does nothing but is syntactically needed.

The loop runs 3 times doing nothing each time because of pass. Then it prints 'Done'.

Pass in function definition

What will be the output of this code?

Python

def greet():
    pass
print(greet())

A greet

B None

C SyntaxError

D '' (empty string)

💡 Hint

Functions without return return None by default.

The function greet does nothing and returns None implicitly. So print outputs None.

Pass in conditional blocks

What is the output of this code?

Python

x = 5
if x > 10:
    print('Greater')
else:
    pass
print('Done')

A Done

B

Greater
Done

C SyntaxError

D No output

💡 Hint

pass does nothing but allows empty blocks.

Since x is 5, the else block runs but does nothing due to pass. Then 'Done' is printed.

Pass in class definition

What will this code print?

Python

class Empty:
    pass

obj = Empty()
print(type(obj))

A <class '__main__.Empty'>

B SyntaxError

C <class 'object'>

D None

💡 Hint

pass allows empty class bodies.

The class Empty is defined with pass. Creating obj is valid. type(obj) shows the class name.

Pass effect on function behavior

What is the output of this code?

Python

def func():
    if False:
        pass
    else:
        return 'Hello'

print(func())

A None

B pass

C SyntaxError

D Hello

💡 Hint

pass does nothing and does not affect flow.

The if condition is False, so else runs and returns 'Hello'. pass does not affect this.
