To get multiple first matches from a regular expression (regex), you can use a loop or a method that allows for multiple matches.


One common approach is to use the re.findall() function in Python's re module. This function returns a list of all matches in a string, rather than just the first match. You can then access the first few matches by slicing the list.


Here is an example using re.findall() in Python:

1
2
3
4
5
6
7
8
9
import re

text = "The quick brown fox jumps over the lazy dog"
pattern = r'w{5}'  # Match words that are exactly 5 characters long

matches = re.findall(pattern, text)

first_two_matches = matches[:2]
print(first_two_matches)


In this example, the regex pattern matches words that are exactly 5 characters long. The re.findall() function returns all the matches, and we use slicing to only get the first two matches in the list.


You can adjust the regex pattern to match whatever criteria you need to get the multiple first matches from the text.
