The current stable version of urllib3
can be checked using several methods. Since package versions change frequently, here are the most reliable ways to find the latest stable version:
Method 1: Check via PyPI (Recommended)
The Python Package Index (PyPI) is the official source for package information:
- Visit the official PyPI website: https://pypi.org/project/urllib3/
- The latest stable version is displayed prominently at the top of the page
- You can also see the release history and download statistics
Method 2: Using pip Commands
Check Installed Version
If you already have urllib3
installed, check its version:
pip show urllib3
This displays detailed package information including the installed version.
Check Latest Available Version
To see the latest version available for installation without installing it:
pip index versions urllib3
Alternative Method (for older pip versions)
If the above command doesn't work, use this trick:
pip install urllib3==nonexistent
This will fail but show all available versions, with the latest at the bottom.
Method 3: Using Python Code
You can check the version programmatically:
import urllib3
print(urllib3.__version__)
Or check the latest version available on PyPI:
import requests
response = requests.get('https://pypi.org/pypi/urllib3/json')
latest_version = response.json()['info']['version']
print(f"Latest urllib3 version: {latest_version}")
Method 4: Check via GitHub
Visit the official urllib3 GitHub repository: - https://github.com/urllib3/urllib3 - Check the latest release in the "Releases" section
Method 5: Using pip list
To see all installed packages and their versions:
pip list | grep urllib3
To check for outdated packages:
pip list --outdated
