I need find a repeated sequences of same my_string = 'ABCD' in string my_data = 'ABCDABCDRRRABCD' and return the longest one 'ABCDABCD'.
If I use result = ([max(i) for i in re.findall(r'((ABCD)\2+)', data)]) It's works fine, but I can't put a variable my_string so I can use it for difference strings in some loop.

To put variable inside of regular expression you can use .format
result = ([max(i) for i in re.findall(r'(({0})\2+)'.format(my_string), my_data)])

1typo? should be ```result = ([max(i) for i in re.findall(r'(({})\2+)'.format(my_string), my_data)])``` – pink spikyhairman May 03 '20 at 18:43

different type of placeholder, both style works fine – Oleg Kobeliatskyi May 03 '20 at 18:59
