Why None as Output? [duplicate]

Answer 1

You print the return value of the print that is returned from function.

def fun(x, y):
    ''' takes an orderd list and an another number
    as input'''

    if y in x:
        return print("it's in the list")
    else:
        return print("number is not in the list")

fun([2,3,4,5], 5)
