How can I check if a string is a valid URL in Python using the validators library and regex with additional validation rules for specific URL formats?

To check if a string is a valid URL in Python using thevalidators library, regex, and additional validation rules for specific URL formats, you can follow these steps: 1. Install thevalidators library:

1
2
3

   pip install validators

2. Import the necessary modules and classes:

1
2
3
4

   import re
   import validators

3. Define a function to check if the string is a valid URL with additional validation rules:

1
2
3
4
5
6
7
8
9
10
11
12
13

   def is_valid_url(url):
  # Check if the URL is valid using the validators library
  if not validators.url(url):
 return False

  # Additional validation rules
  # Add any additional validation rules as per your requirements
  if not re.match(r'^https?://', url):
 return False

  return True

4. Call theis_valid_url function and pass the string to be checked:

1
2
3
4
5
6
7

   url = "https://www.example.com"
   if is_valid_url(url):
  print("Valid URL")
   else:
  print("Invalid URL")

In theis_valid_url function, thevalidators.url() function from thevalidators library is used to validate the URL format. If the URL format is valid, the function proceeds with additional validation rules specific to your requirements. A regular expression (^https?://) is used to check if the URL starts with either "http://" or "https://". This is just an example of an additional validation rule. You can modify the regex pattern to suit your specific requirements. If the URL passes both the format validation using thevalidators library and any additional validation rules specific to your requirements, the function returnsTrue, indicating that the URL is valid. Otherwise, it returnsFalse. You can modify the code to include any additional checks or handle different types of URL formats. This approach allows you to dynamically check if a string is a valid URL, considering both thevalidators library, regex pattern matching, and any additional validation rules for specific URL formats, in your Python programs.
