A closer look at the different methods of Django version querying

Django is a powerful Python web framework that is widely used in web development. During development, it is very important to know which version of Django you are currently using, as different versions may have different features and improvements. This article will introduce in detail several common ways to check the Django version and provide specific code examples.

1. Use the command line to view the Django version

Enter the following command on the command line to directly view the Django version information:

python -m django --version

Run this After the command, the Django version number used by the current project will be displayed, for example:

Django 3.2.3

2. Use code to view the Django version

import django

print("Django版本号：", django.get_version())

print("Django副版本号：", version_info[1])
print("Django修订版本号：", version_info[2])
