yea very good explaination :). cheers chrys Am 09.06.2018 um 01:58 schrieb Linux for blind general discussion:
Something to keep in mind when dealing with software written in Python is that not all programs written in Python2 have either been upgraded to use Python3 or been deprecated. As a result, many distros, Debian included have both Python2.7 and the latest Python3 to ensure compatibility with both old and new applications. In most cases, this doesn't cause problems as most Python applications invoke the correct version of Python without user input, but if you're using one of Python's own utilities not specifying the version will often cause a redirection to the Python2.7 version. I.e. the command python is usually a symbolic link to python2.7 whereas python3 is the command that will invoke the latest Python3 installed on your system. Similarly, the pip command will invoke pip for installing Python2 applications and you need to specify pip3 to install Python3 applications. On my own system, with most of tits software sourced from Debian Unstable, I have Python3.6 installed and no Python2.7 installed and don't have a python command(tab completion gives me python3 from pyt).
