Extract capture group, multiple timesfinditer also works, but you get the full Match object for each capture import re pattern = r'a(\d+)' re.findall(pattern, 'a1 b2 a32') # >>> ['1', '32'] Extract first occurrence of regexThis matches a pattern anywhere in the string, but ...
Matches whatever regular expression is inside the parentheses, and indicates the start and end of a group;the contents of a group can be retrieved after a match has been performed, and can be matched later in the string with the\numberspecial sequence, described below. To match the literals'...
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...

Regular expression with named capture groups may also be used. The parsed parameters replace existing values. Example: --metadata-from-title "%(artist)s - %(title)s" matches a title like "Coldplay - Paradise". Example (regex): --metadata-from-title "(?P<artist>.+?) - (?P.+)" --...

Instead of having lots of different regexes, you can have one top level regex that can match the whole line, dividing it up into capture groups with brackets (()). The capture groups have no effect on the actual matching process, but they do affect the match object that results from the...
