How to find all matches to a regular Expression in Python?

To find all matches to a regular expression in Python, you can use the re module. The re module provides various functions for working with regular expressions. Here’s an example of how to find all matches:

import re

text = "Hello, my name is John. My email address is john@example.com. Please contact me."

pattern = r'\b\w+@\w+\.\w+\b'  # Regular expression pattern to match email addresses

matches = re.findall(pattern, text)

print(matches)

In this example, we have a text that contains an email address. We define a regular expression pattern using a raw string r'\b\w+@\w+\.\w+\b' to match email addresses. This pattern matches one or more word characters (\w+), followed by the @ symbol, then one or more word characters, a dot, and one or more word characters again.

We use the re.findall() function to find all non-overlapping matches of the pattern in the text. The findall() function returns a list of all matches found.

Finally, we print the matches, which in this case is the email address:

['john@example.com']

The output shows the email address found in the text.

You can adjust the regular expression pattern (pattern) based on your specific matching requirements.
