Compiled regular expression objects support the following methods and attributes:
string[, pos[, endpos]]) |
None
if the string does not
match the pattern; note that this is different from a zero-length
match.
Note: If you want to locate a match anywhere in string, use search() instead.
The optional second parameter pos gives an index in the string
where the search is to start; it defaults to 0
. This is not
completely equivalent to slicing the string; the
'^'
pattern
character matches at the real beginning of the string and at positions
just after a newline, but not necessarily at the index where the search
is to start.
The optional parameter endpos limits how far the string will
be searched; it will be as if the string is endpos characters
long, so only the characters from pos to endpos -
1
will be searched for a match. If endpos is less than
pos, no match will be found, otherwise, if rx is a
compiled regular expression object,
rx.match(string, 0, 50)
is equivalent to
rx.match(string[:50], 0)
.
string[, pos[, endpos]]) |
None
if no
position in the string matches the pattern; note that this is
different from finding a zero-length match at some point in the string.
The optional pos and endpos parameters have the same meaning as for the match() method.
string[,
maxsplit = 0 ]) |
string[, pos[, endpos]]) |
string[, pos[, endpos]]) |
repl, string[, count = 0 ]) |
repl, string[,
count = 0 ]) |
0
if no flags were provided.
