Solution

You can use the command below and then select the alternative version to change the python version.

!sudo update-alternatives --config python3

Output:

There are 2 choices for the alternative python3 (providing /usr/bin/python3).

  Selection    Path                Priority   Status
------------------------------------------------------------
* 0            /usr/bin/python3.7   2         auto mode
  1            /usr/bin/python3.6   1         manual mode
  2            /usr/bin/python3.7   2         manual mode

Press <enter> to keep the current choice[*], or type selection number: 1
update-alternatives: using /usr/bin/python3.6 to provide /usr/bin/python3 (python3) in manual mode 

To check the python version use the following code.

python --version # 3.6.9
