Question

Hi, Looking for some help with this Python question as follows:

Consider the following Python program:

def fun(x, y):

return x * y

a = fun(2, 3)

b = fun("2", 3)

print(a, b)

What does the function evaluate to? What would happen if we replace the last statement print a, b with print a + b?

Thanks for any help.

Answer 1

def fun(x, y):

return x * y

a = fun(2, 3)

b = fun("2", 3)

print(a, b)

here a will become 2*3 i.e. 6

b will become "2"*3 i.e. repeat string 2 three times.Hence "222".

Hence function will multiply x by y if it is number .But if is string it just append x to itself y times.

What would happen if we replace the last statement print a, b with print a + b?

It will give error because we cant just add int and string

Output of above is

(6, '222')
