regex - How to match exact "multiple" strings in Python -

i've got list of exact patterns want search in given string. i've got real bad solution such problem.

pat1 = re.compile('foo.tralingstring') mat1 = pat1.match(mystring)  pat2 = re.compile('bar.trailingstring') mat2 = pat2.match(mystring)  if mat1 or mat2:     # whatever  pat = re.compile('[foo|bar].tralingstring') match = pat.match(mystring) # doesn't work 

the condition i've got list of strings matched exactly. whats best possible solution in python.

edit: search patterns have trailing patterns common.

you trivial regex combines two:

pat = re.compile('foo|bar') if pat.match(mystring):     # whatever 

you expand regex whatever need to, using | separator (which means or in regex syntax)

edit: based upon recent edit, should you:

pat = re.compile('(foo|bar)\\.trailingstring'); if pat.match(mystring):     # whatever 

the [] character class. [foo|bar] match string one of included characters (since there's no * or + or ? after class). () enclosure sub-pattern.
