python - String filtering commas and numbers -

-

i want filter string in python, commas , , numbers [0-9].

import re x="$hghg54646jhgjh,54546654" m=re.sub("[^0-9]","",x) print(m)

the result is:

5464654546654

instead of:

54646,54546654

with current code, match [0-9]. add comma , valid character, , use backslash escape literal (\,):

import re x="$hghg54646jhgjh,54546654" m=re.sub("[^0-9\,]","",x) print(m)

outputs:

54646,54546654

the docs have further information regarding other special characters must escaped backslash acquire literal, such ? , *.
