AttributeError Regex

[linh_py]

Your string start with one white-space and end with two,when using ^ and $ it most match the begin/end of string exactly on each line.
Could be written like this numRegex = re.compile(r"^\s\d{1,3}(,(\d{3})).*$")
Or if strip of white-space it will also work.

import re

numRegex=re.compile(r"^\d{1,3}(,(\d{3}))*$")
mo = numRegex.search(" 12,124,123,221  ".strip())
print(mo.group())

oh, yeah, i don't know it before. tks verymuch. So it doesn't seem very convenient
