I'm trying to define a variable accesible to all my files (modules) in a Python Project. To do so, I defined a file Config.py, in there I tried both

#Config.py  ##1

import pandas as pd
GDF=pd.DataFrame()


#Config.py  ##2

import pandas as pd

def init():
  global GDF
  GDF=pd.DataFrame()

The structure of the program is to have a table, and across several modules get some rows. I tried

#Functions.py 
import Config

def RandomFunct():
   Config.GDF.append([a,b,c,d],ignore_index=True)

#Main.py
import Config

some code
print(Config.GDF)

What I get is an empty DataFrame. I tried all possible alternatives exposed in this thread Using global variables between files? but to no avail.

Can anybody enlighten me on how to do it?

It looks like you are not calling init() in main.py. Also you need to store the changes to DF

try 

# Config.py
import pandas as pd

def init():
    global GDF
    GDF=pd.DataFrame()


#Functions.py 
import Config

def RandomFunct():
   Config.GDF = Config.GDF.append([a,b,c,d],ignore_index=True)

# main.py

import settings
import Functions

Config.init()
Functions.RandomFunct()
print(Config.GDF)

  • Apparently, what was amiss was that I did `Config.GDF.append()` instead of doing `Config.GDF=Config.GDF.append()`. It is now solved, thank you very much – puppet Jun 08 '18 at 21:35
