How do I know python path on linux ubuntu?

Question

In ubuntu linux if we want to set up python path we do something like this:

export PYTHONPATH=/etc ...

Now, how I would know what the current path I have?

• user707650: printenv PYTHONPATH?
• aquavitae: You question is not very clear, do you want to see the variable in the terminal or in python? You've got both answers below, but you should make the question clearer.

Answer 1

You can type which python on the ubuntu terminal and it will give the Python installed location path.

Answer 2

First, I hope you don't really set PYTHONPATH=/etc, /etc is for configuration files, not python libraries.

You can see what an environment variable is set to by using echo, e.g.: echo $PYTHONPATH. If the variable has not been set it will be blank. You can also use env to get a list of all environment variables, and couple with grep to see if a particular one is set, e.g. env | grep PYTHONPATH.

• Mero: Ya it was bad example to use /etc .

Answer 3

use printenv command, it will print all the environment variables, to only print PYTHONPATH use: printenv PYTHONPATH

Answer 4

Command:

which python

gives path to python

as:

which python3

gives python3 path

• suitendaal: This is not the PYTHONPATH environment variable as is referred to in the question
