[Tutor] Even More Converter!

[Kepala Pening]

sorry, I forgot that re search from the front of the string.

import re

putComma = lambda x: (','.join(re.findall("\d{1,3}", str(x)[::-1])))[::-1]

print putComma(1234567)     # 1,234,567
print putComma(12345678)    # 12,345,678
print putComma(123456789)   # 123,456,789
