Behavior |
Example |
| re.match(pattern, string, flags=0) |
Match only at start |
re.match(r’\d+’, ‘123abc’) |
| re.search(pattern, string, flags=0) |
Match anywhere in string |
re.search(r’\d+’, ‘abc123def’) |
| re.findall(pattern, string, flags=0) |
Returns all matches as list |
re.findall(r’\d+’, ’12, 34′) → [’12’,’34’] |
| re.finditer(pattern, string, flags=0) |
Returns iterator of Match objects |
for m in re.finditer(r’\d+’, ’12, 34′): print(m.group()) |
| re.sub(pattern, repl, string, count=0, flags=0) |
Replace matches with repl |
re.sub(r’\d+’, ‘#’, ‘a1b2’) → ‘a#b#’ |
| re.subn(pattern, repl, string, count=0, flags=0) |
Same as sub + returns tuple (new_string, num_subs) |
re.subn(r’\d+’, ‘#’, ‘a1b2’) → (‘a#b#’, 2) |
| re.split(pattern, string, maxsplit=0, flags=0) |
Split string on regex matches |
re.split(r’\s+’, ‘a b c’) → [‘a’,’b’,’c’] |
