The findall method of re module
The findall method of the re module returns a list of all matches with a regular expression. If the regular expressions are placed in pockets, the method will return a tuple. In the first parameter of the method, we specify the regular expression to search for, and in the second parameter, the string to search for. In the third optional parameter, you can specify flags for additional regular expression settings. The method checks all matches, searching for them from left to right.
Syntax
import re
re.findall(regular expression, string, [flags bunting])
Example
Let's find all matches with a regular expression in a string:
txt = '12 43 56 ab'
res = re.findall('\d+', txt)
print(res)
Result of code execution:
['12', '43', '56']
Example
Now let's find all the matches in the regular season pockets:
txt = '12 43 56 ab'
res = re.findall('(\d)(\d)', txt)
print(res)
Result of code execution:
[('1', '2'), ('4', '3'), ('5', '6')]
