re.findall

Find all non-overlapping matches of a regular expression.

Python 3.13
re.findall(pattern, string, flags=0)

=default value

pattern: The regular expression.
str | Pattern
string: The string to search in.
str
flags: Flags, 0 (no flags) by default; combine several with |.
intOptional
re.IGNORECASEre.MULTILINEre.DOTALLre.VERBOSEre.ASCII

Return value

A list of strings; with one group in the pattern, a list of its values; with several groups, a list of tuples. An empty list [] if there are no matches.

Examples

All numbers in a string

Python 3.13
import re
print(re.findall(r'\d+', '12 drummers, 11 pipers'))
['12', '11']

Tuples of groups

Python 3.13
import re
print(re.findall(r'(\w+)=(\d+)', 'width=20 height=10'))
[('width', '20'), ('height', '10')]

Details

If the pattern has groups, the result contains the group values rather than the whole match, which often causes surprises. To group part of a pattern without capturing it, use (?:...). If you need match positions, re.finditer yields Match objects.
