python - Find several strings with regular expressions -

-

i'm looking or capability match on several strings regular expressions.

# find either "-hex", "-mos", or "-sig" # result -hex, -mos, or -sig # see want rid of double quotes around these 3 strings. # other double quoting ok. # i'd like. messwithcommandargs =  ' -o {} "-sig" "-r" "-sip" ' messwithcommandargs = re.sub(             r'"(-[hex|mos|sig])"',             r"\1",             messwithcommandargs)

this works:

messwithcommandargs = re.sub(             r'"(-sig)"',             r"\1",             messwithcommandargs)

square brackets character classes can match single character. if want match multiple character alternatives need use group (parentheses instead of square brackets). try changing regex following:

r'"(-(?:hex|mos|sig))"'

note used non-capturing group (?:...) because don't need capture group, r'"(-(hex|mos|sig))"' work same way since \1 still quotes.

alternative use r'"-(hex|mos|sig)"' , use r"-\1" replacement (since - no longer part of group.
