Installing Python on Linux is actually easy. The only difficult part could be that there are many distributions that needs different installation commands.
First check in your command line if you don't already have python3 installed:
$ python3 --version
If there will appear "Python" and version number (e. g. Python 3.8.2)
and the version is higher than 3.6 you are done here so continue with
other section tkinter check.
If there will be "Python" and version lower than 3.6, ask coach.
If bash: python3: command not found or something similar will appear
you will have to install Python3.
Command depends on your distribution.
$ sudo dnf install python3
$ sudo apt-get install python3
If you are using some other distribution we expect that you already know how to install programs. If not try to ask Google.
For conda installation use this link and choose Anaconda.
Then you have to add full path to /......./Continuum/anaconda3/Scripts (instead of dots there will be something different regarding where you installed it) to your environment variable PATH - try to find out by yourself (but if you will have some troubles contact us). You will know that it's been added successfully by typing into your command line:
conda --help
After successful installation follow how to create virtual environment
