python import file from same directory

1import os

3    print(f.read())

1import mymodule
2
3mymodule.say_hello()

1# To call say_hello() from inside script.py, we can write in script.py:
2
3import mymodule
4
5mymodule.say_hello()

1import subdir.mymodule
2
3subdir.mymodule.say_hello()

1# In a file system path, we would separate the components of a path 
2# using / (Linux, macOS, etc.) or \ (Windows). In a Python import statement, 
3# however, we separate the path components using a dot (.).
4
5import subdir.mymodule
6
7subdir.mymodule.say_hello()

1# Then if we're using Python 3.3 or higher, we can write in script.py:
2
3import subdir.mymodule
4
5subdir.mymodule.say_hello()
