python-regexHow to match certain amount of digits with Python regex?

Python regex can be used to match certain amount of digits. The \d character class is used to match any single digit. To match a specific amount of digits, the {n} quantifier can be used, where n is the number of digits to match. For example, to match exactly 5 digits, the regex \d{5} can be used.

import re

# Match exactly 5 digits
pattern = r"\d{5}"

# Test string
test_string = "1234567890"

# Match the pattern
result = re.match(pattern, test_string)

# Print the result
print(result)

Output example

<re.Match object; span=(0, 5), match='12345'>
