How to import other Python files?

Question

How do I import other files in Python?

1. How exactly can I import a specific python file like import file.py?

2. How can I import a folder instead of a specific file?

3. I want to load a Python file dynamically at runtime, based on user input.

4. I want to know how to load just one specific part from the file.

For example, in main.py I have:

from extra import *

Although this gives me all the definitions in extra.py, when maybe all I want is a single definition:

def gap(): 

print 

print

What do I add to the import statement to just get gap from extra.py?

You can use the below-mentioned code to import a specific Python file at 'runtime' with a known name:

import os 

import sys

scriptpath = "../Test/MyModule.py" 

sys.path.append(os.path.abspath(scriptpath)) 

import MyModule
