Python Regex can be used to match a year with the following steps:

1. Create a regular expression pattern to match a year using the re module:

import re
year_pattern = re.compile(r'\d{4}')

2. Use the findall() method to search for the pattern in a string:

year_matches = year_pattern.findall('The year is 2020')

3. The findall() method will return a list of matches:

print(year_matches)

['2020']
