Question

What will be the output of the following code?

def f1(a,b=1):

     print(a+b,end='-')

c=f1(1,2)

print(c,sep='*')

Options

• 3−2

• 3−2*

• 3−None

• 3*None

Answer 1

3−None

Explanation:

• Function Call: When f1(1, 2) It is called, it prints the sum 1+2 (which is 3) and uses the end='-' parameter, resulting in the output 3-.
• Return Value: The function f1 does not have a return statement. In Python, if a function doesn’t explicitly return a value, it returns None. Therefore, the variable c is assigned the value None.
• Final Print: The statement print(c, sep='*') then prints the value of c, which is None.
• Combined Output: Joining the two print actions together gives 3-None.
