How to Specify a Python Package Version?

In Python, you can specify a specific version of a package in your code by using the import statement and specifying the version number using the syntax package_name==version_number.

Here’s an example:

import requests==2.25.1

response = requests.get('https://www.google.com')
print(response.status_code)

In this example, we are importing the requests package with version number 2.25.1. We then use the requests.get() function to make an HTTP request to Google’s homepage and print the response status code.

Note that this syntax is only valid if you have previously installed the package with the specified version number. You can install a specific version of a package using pip by specifying the version number using the same syntax:

pip install package_name==version_number

For example, to install requests version 2.25.1, you would run the following command:

pip install requests==2.25.1

If you do not specify a version number when installing a package, pip will install the latest available version of the package by default.

When working with packages and dependencies in Python, it’s generally a good practice to use a package manager like pip or conda to manage package installation and versioning. This can help you avoid version conflicts and ensure that your code is running with the expected package versions.
