Question

I have two Python scripts in two different locations and cannot be moved. What is the best way to send information between the two scripts?

say for example in script1.py i had a string e.g.

x = ‘teststring’

then i need variable ‘x’ passed to script2.py, which saves the variable ‘x’ to a text file?

Any ideas?

Answer 1

You just import it.

#script2.py
from script1 import x

To make the script2 find the script1, the script1 file must be in the module search path

Here’s an example:

First we create a dir and display the value of the module search path:

$mkdir some_dir
$echo $PYTHONPATH

It’s nothig. Then we create a file with the variable x initialized to “hola” in that directory:

$cat >some_dir/module_a.py <<.
> x = "hola"
> .

And we create another python file to use it:

$cat >module_b.py<<.
> from module_a import x
> print x
> .

If we run that second script we got an error:

$python module_b.py 
Traceback (most recent call last):
  File "module_b.py", line 1, in <module>
    from module_a import x
ImportError: No module named module_a

But, if we specify the some_dir in the module search path, and run it again, should work:

$export PYTHONPATH=some_dir
$python module_b.py 
 hola
