Question

a file content just like this:

##this is the comment

but this is not comment '####', LOL   # this is a normal comment

I just want to filter all comments and get the filtered content, But I don’t know how to avoid to filter the pound signs which are not comments.

fileLines = [line.strip() for line in file if '#' != line[0] ]

this code just can filter the comment sign which is the first character of a line.

the result I want is just like the following line:

but this is not comment '####', LOL

Answer 1

import shlex
filelines = [' '.join(shlex.split(line,True)) for line in file]

See the shlex docs for more information.
