Running a .py script from bash, how can I pass a python variable back to the terminal once the .py is done running?

Question

For example, in bash:

python my_py.py
    # i get some variable my_var

Back to bash. I want to have $my_var!

print the variable, and only the variable to terminal. Then, in bash you can assign the output to a variable using process substitution: `myVar=$(python my.py)` — hek2mgl, Aug 23 '13 at 10:51

You can write your variable and its value into an ini file from the python script.

In Values.ini file

my_var="value"

After executing python script, just invoke Values.ini using . operator

. Values.ini

Now your shell variable $my_var will be having the assigned value. The advantage with this method is that you can assign any number of variables like this.

var1="value1"

var2="value2"

var3="value3"

Ok, I'll try that, thanks. By the way, in your answer you should take "In Values.ini file" out of code format. That confused me at first. – brastein Aug 23 '13 at 11:21
@brastein Thnx. Done :) – Antarus Aug 23 '13 at 11:27
using `os.environ` would be both more appropriate and faster, and you can declare as many variables as you want – This company is turning evil. May 15 '14 at 13:09
