Regular Expression - Documentation

Introduction

Number validation in Python is crucial for ensuring data integrity in various applications. Python's re module can be used to validate numbers using regular expressions. A common regex pattern for validating integers might be ^\\d+$.

Number Regex

The regex for validating numbers can vary depending on whether you're validating integers, decimals, or formatted numbers.

The Number Regex Pattern

  • Integers: ^\\d+$

  • Decimals: ^\\d+\\.\\d+$

  • Formatted Numbers (like 1,000): ^(\\d{1,3}(,\\d{3})*|\\d+)(\\.\\d+)?$

How to Validate Numbers in Python?

To validate numbers using regex in Python:


import re

def is_valid_number(number):
    number_regex = re.compile(r'^\d+$')  # Adjust regex as needed
    return bool(number_regex.match(number))

print(is_valid_number("12345"))  # True for integer

Uses of Number Regex Validation

  1. Data Validation: Ensuring that numerical inputs in applications or forms are valid.

  2. Data Processing: Cleaning and standardizing numerical data in datasets.

What next?

Python's regex capabilities provide a powerful tool for number validation. For more comprehensive number format validations, including complex scenarios, Akto's regex validator can be an invaluable resource.
