in xyz.py

import abc as abc print(abc.DB) its giving empty data frame.

Need a solution how to access a DataFrame in multiple files.

Answer 1

You can make it work by having the following: abc.py :

import pandas as pd

df = pd.DataFrame([[0, 0, 0], [1, 1, 1], [2, 2, 2]], ["one", "two", "three"])

xyz.py :

# you could also write "from test import df"
from test import *

print(df)

The output I get from running xyz.py is this, just as expected:

       0  1  2
one    0  0  0
two    1  1  1
three  2  3  4

This should work for you.
