从另一个文件调用 python function

Question

I am trying to reference a variable from one python file to another.

I have a base file that has a variable value, current_time and I want to call this variable in another python function that is in another python file.

This is what I tried doing:

From the file I am trying to call the variable:

ref_path = os.path.split(os.getcwd())[0]
ref_path = os.path.join(ref_path, "folder_1", "folder_2", "folder_3")

Now that I am pointing to the destination folder when I try doing

from ref_path import function as function
 

I am getting an error ModuleNotFoundError: No module named 'ref_path'

I am trying to call function.current_time

Answer 1

Add the path to base file in your syspath and import the variable.

import sys
sys.path.append(ref_path)

from function import *
# Now you can use the variable

Answer 2

Could you import the file?

assuming the ref path is the directory next to this file you could try this:

import os

fullPath = os.path.realpath(__file__)  #this file
thisDir = os.path.dirname(fullPath) # this files directory

from ref_file import ref_module 

print(ref_module.GetCurrentTime())
