Extract capture group, multiple times finditeralso works, but you get the fullMatchobject for each capture importrepattern=r'a(\d+)'re.findall(pattern,'a1 b2 a32')# >>> ['1', '32'] Extract first occurrence of regex This matches a pattern anywhere in the string, butonly once. ...
Grouping also enables capturing. Using parentheses, you can capture and refer to the matched substring later. For example, consider the pattern: /(ab)+c/. In this pattern, the group (ab) is captured. If the string “ababc” matches this pattern, you can access the captured group and ret...
If <regex> contains more than one capturing group, then re.findall() returns a list of tuples containing the captured groups. The length of each tuple is equal to the number of groups specified:Python 1>>> re.findall(r'(\w+),(\w+)', 'foo,bar,baz,qux,quux,corge') 2[('foo...
In this tutorial, you'll learn how to remove or replace a string or substring. You'll go from the basic string method .replace() all the way up to a multi-layer regex pattern using the sub() function from Python's re module.
