I made this program, but it doesn't work like I want.:

a = int(0)
for a in range (11,21):
    r = '({},{},{})'.format(a, a ** 2, a ** 3)
print(r)

I'd like to have squares and cubes numbers from 11 to 20. However, it shows only for number 20. Where is my mistake please?

If you indent your final line, it will do what you want. You can also remove the first line, it doesn't do anything useful.

thank you

that works fine.
