First of all, it is stated that there is a built-in Python in the Deepin 20.2 system, and the Python2 series version is used by default. Although this version is very old, Python2 is at the bottom of the system and will not be easily removed or changed to the default Python3 version.

Description

Deepin 20.2 comes with versions 2.7 and 3.7, which can be called using python3. Pip corresponds to Python2,pip3 and corresponds to python3. Basically, all commands correspond to each other, followed by a 3.

The current default pyhon command points to python2. Because in the current situation, many of the underlying layers rely on Python2, so users should not change the default. As for when to change the version, it needs to be migrated to python3 first.

You can install Python3 by yourself, and then change the default Python of the system to Python3.

The specific steps are as follows:

Sudo apt install python3 python3-pip

2. View the Python command file:

$ls / usr/bin/python*-lh

3. Set the system default Python to Python3:

Sudo update-alternatives-install / usr/bin/python python / usr/bin/python3.7 2

Sudo update-alternatives-- install / usr/bin/python python / usr/bin/python2.7 1

4. After modifying the default Python, check the version of the default Python:

$which python

/ usr/bin/python

$python-version

Python 3.7.3

5. To switch the default Python between Python2 and Python3, you can run the following command:

Sudo update-alternatives-config python

Note: this method is easiest if all users on the same machine use Python3 by default.
