Easily master the skills of Django version query

Django version query skills: easy to master, specific code examples are required

Introduction:
Django is an open source web framework written in Python language and is widely used in web application development. As a mature and stable framework, Django’s versions are updated more frequently. During the development process, sometimes we need to query the Django version number currently in use, and perform corresponding compatibility processing according to different versions. This article will share with you some easy-to-master Django version query techniques and provide specific code examples.

1. Use the command line to query the version number:
In the terminal or command line environment, we can query the current Django version number through the following command.

python -m django --version

After executing this command, the currently installed Django version number will be displayed, for example:

3.2

2. Use Python code to query the version number:

1. Import django Module

To use Django-related functions, you first need to import the django module in the Python code. The sample code is as follows:

import django

2. Query version number

Through the get_version function of the django module, you can get the currently running Django version number. The sample code is as follows:

print(django.get_version())

Executing the above code will output the current Django version number.

3. Django version comparison

During the development process, we may need to perform different compatibility processing based on the current Django version. Below is a simple example that shows how to use conditional statements to execute different code logic based on different version numbers.

if django.VERSION >= (3, 2):
    # 处理兼容性问题的代码
    print("当前版本支持相关功能")
else:
    # 处理其他情况的代码
    print("当前版本不支持相关功能")

In the above code, we compare the current version number with (3, 2) to determine whether Django meets the specific version requirements, thereby executing the corresponding code logic.

4. Use the django.conf module to query the version number

In addition to the above methods, you can also use the ## in the django.conf module #settingsObject queries the current version number.

from django.conf import settings

print(settings.VERSION)

You can get the current Django version number through

settings.VERSION.

Summary:

During the development process, it is very important to query and understand the Django version number currently used, which can help us perform corresponding compatibility processing according to different versions. This article introduces how to query the Django version number from the command line, Python code and
django.conf module, and gives corresponding code examples. I hope it will be helpful for everyone to learn and use Django.
