how to import file from another directory in python

import sys
# sys.path is a list of absolute path strings
sys.path.append('/path/to/application/app/folder') # <-- relative path

import your_file

import python script from another directory

#Unfortunately, Python will only find your file if your file is in the systems path. But fear not! There is a way around this!
#Using python's sys module, we can add a directory to the path just while Python is running, and once Python stops running, it will remove it from the path.
#You can do this by:

import sys
sys.path.insert(0, '/path/to/application/app/folder')
import [file]

importing python module from different directory

# test.py
import sys
# append current python modules' folder path
# example: need to import module.py present in '/path/to/python/module/not/in/syspath'
sys.path.append('/path/to/python/module/not/in/syspath')

import module

python import file from different directory

# By default, you can't. When importing a file, Python only 
# searches the current directory, the directory that the 
# entry-point script is running from, and sys.path which includes
# locations such as the package installation directory 
# (it's actually a little more complex than this, but this covers
# most cases).

# you can however, add to the path at runtime

import sys
# insert at position 1 in the path, as 0 is the path of this file.
sys.path.insert(1, '/path/to/application/app/folder')

import file

import python file from another directory

from application.app.folder.file import func_name

import python code from another directory

The solution is very simple, just add a __init__.py file to the directory
where the package or code you want to import is, and then python will treat
that directory as a package. Then is as simple as just importing the code
like any other third party package. Below is a diagram of best practices 
doing this.


package/
    |
    |----- __init__.py (Empty file)
    |------- main_module.py (Contains: import subpackage_1.module_1)        
    |------- module_0.py (Contains: print('module_0 at parent directory, is imported'))
    |           
    |
    |------- subpackage_1/
    |           |
    |           |----- __init__.py (Empty file)
    |           |----- module_1.py (Contains: print('importing other modules from module_1...')
    |           |                             import module_0
    |           |                             import subpackage_2.module_2
    |           |                             import subpackage_1.sub_subpackage_3.module_3)

    |           |----- sub_subpackage_3/
    |                        |
    |                        |----- __init__.py (Empty file)
    |                        |----- module_3.py (Contains: print('module_3 at sub directory, is imported')) 
    |
    |------- subpackage_2/ 
    |           |
    |           |----- __init__.py (Empty file)
    |           |----- module_2.py (Contains: print('module_2 at same level directory, is imported'))

importing a python file from another folder

import sys
# sys.path is a list of absolute path strings
sys.path.append('/path/to/application/app/folder')

import folder from another folder python

sys.path.insert(1, '/path/to/application/app/folder')

how to import somthing from another directory in pyhon

# some_file.py
import sys
# insert at 1, 0 is the script path (or '' in REPL)
sys.path.insert(1, '/path/to/application/app/folder')

import file
