is it necessary to place module in root directory to import python code example

Example 1: 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

Example 2: import local module python

# If the module is in the same directory:
import <module_name>

# If the module isn't in the same directory:
import sys
# insert at 1, 0 is the script path (or '' in REPL)
sys.path.insert(1, '/path/to/application/app/folder')

import <module_name>
