Python - how to multiply characters in string by number after character ...

Here's a simplistic approach: string = 'A3G3A' expanded = '' for character in string: if character.isdigit (): expanded += expanded [-1] * (int (character) - 1) else: expanded += character print (expanded) OUTPUT: AAAGGGA.
