Examples of how to use the validators module in Python

Hi 🙂🖐

We know that validators are very important; they're used in many things like email, usernames, and passwords. In this post, I will share with you how to make validation by using a module called validators.

First, you need to install validators

pip install validators

[1] - URL Validation

import validators

print(validators.url('https://dev.to')) # True

validators.url returns true' if the URL is valid. If not validated, it will return ValidationError.

import validators

print(validators.url('https//dev.to')) 

result

ValidationError(func=url, args={'value': 'https//dev.to'})

[2] - Email Validation

import validators

print(validators.email('test@test.com')) # True

validators.email returns true' if Email is valid. If not validated, it will return ValidationError.

[3] - Domain Validation

import validators

print(validators.domain('test.com')) # True

[4] - Card Numbers Validation

You can find Card Numbers to test from here : https://support.bluesnap.com/docs/test-credit-card-numbers

import validators

print(validators.card_number('6250941006528599')) # True

You can choose the card type that you want to validate. You have many types, like visa, Mastercard, Amex

Validate Visa card number

import validators

print(validators.visa('4263982640269299')) # True

Validate mastercard number

import validators

print(validators.mastercard('5425233430109903')) # True

Validate amex number

import validators

print(validators.amex('374245455400126')) # True
