Trying to have an output repeat

[magnifik]

How do you make a string repeat itself for a given number of times?
For example, if I wanted to make "3y" print out "yyy" on the screen (it prints "y" 3 times because the number in the input is 3).. how would i do this using functions?

you could just parse the input string; but of course, you will need to include some specifications, or the input/output you want can be very vague ('33y') can be 33 times of y or 3 times of 3y.
