28.5.3. Compiled regular expression objects

Compiled regular expression objects returned by re.compile() have these methods:

.match(s[,[p_s][,p_e]]): If the start of string s matches, return a MatchObject; if there is no match, return None. If p_s is given, it specifies the index within s where matching is to start; this defaults to 0. If p_e is given, it specifies the maximum length of s that can be used in matching.
.pattern: The string from which this object was compiled.
.search(s[,[p_s][,p_e]]): Like match(), but matches anywhere in s.
.split(s[,maxsplit=m]): Like re.split().
.sub(R,s[,count=c]): Like re.sub().
