I have two Python scripts. The main script import the second script

test_credenziali.py (main script)

#!/usr/bin/env python
# coding=utf-8
# Copyleft Roberto Marzocchi - Gter srl Innovazione in Geomatica Gnss e Gis
import os,sys,shutil,re,glob, getopt
dirname0 =os.path.dirname(sys.argv[0]) 

#dirname = os.path.dirname(os.path.realpath(__file__)) #NameError: name '__file__' is not defined

dirname2= os.getcwd()
print('The path of the python script is ', dirname0 ) 
#print('The path of the python script is ', dirname ) 
print('The path of the python script is ', dirname2 ) 

# here i like to use the dirname variable
sys.path.insert(0, r'C:\Users\assis\Desktop\script_test')
from credenziali import *
print(host) 

credenziali.py

host='domain.it'

I save both script in the same folder (e.g on my desktop) C:\Users\assis\Desktop\script_test

and if I use the following line before the import of credenziali.py it works

sys.path.insert(0, r'C:\Users\assis\Desktop\script_test')

Nevertheless I like to use relative path in order to call the credenziali.py script. Using python normally it works or I can use the command

dirname = os.path.dirname(os.path.realpath(__file__))

to obtain the path of the main script.

Using the QGIS Python console it doesn't work.

What I believe is, (I may be wrong) that this happens because when you run a plugin the scripts are compiled and the files created, with extension .pyc are saved in the py_cache folder of your plugin.

But is Python supposed to be an interpreted language? Yes, but when you import a module, in this case os, that module is compiled in the .pyc file.

In the console I suppose that file is not accessible, or is temporary.

Let's hope a guru gives us better information.

  • Probably you are right. The strange thing is that using different console (e.g. the visualcode console for python) I can obtain the dirname without .pyc file – Roberto Marzocchi Sep 30 '20 at 6:10
