Question

I have a program that prints multiplication tables.

def print_tables(input):
    for i in xrange(1,11):
        print "%s x %s = %s" %(input, i, input*i)

user_input = raw_input("What do you want multiplied ten fold? ")

if(user_input.isdigit()):
    print_tables(int(user_input))

else:
    print_tables(user_input)

If the user enters a string "a", I would expect the output to be:

a x 1 = a
a x 2 = aa
a x 3 = aaa
a x 4 = aaaa
a x 5 = aaaaa
a x 6 = aaaaaa
a x 7 = aaaaaaa
a x 8 = aaaaaaaa
a x 9 = aaaaaaaaa
a x 10 = aaaaaaaaaa

Calling the print_tables function in both the if and else blocks does feel a bit redundant to me.

Is there a better way in Python to call the print_tables function regardless of the parameter type?

Answer 1

print_tables(int(user_input) if user_input.isdigit() else user_input)
