when I try to check python version in Centos7 by typing command
1) python --version
-bash: /usr/local/bin/python3.6: No such file or directory
OR
2) which python
"alias python='/usr/local/bin/python3.6'.
Could anyone explain me why it shows like this instead of showing python version?
Thanks.
In order to sum up, for future people who will look in this question:
when installing different versions of python on linux using package manager (in this case yum because you are using CentOS, but it might be apt or something else) linux installs the side-by-side, meaning you have all of the versions installed together.
If you want to use a specific version other than your linux distribution diffault one you need to call it explicitly (i.e. python3.6 or python3.8)
Make sure you are looking for the wanted python version on the right path.
When you want to run some version of python after installing it I suggest you to just write python in the bash and just hit tab+tab and the bash will suggest all the installed versions in the $PATH.
