Modules
Modules are single Python files that can be imported. Any python file can be a module. For example, if I have two Python files: module.py
and hello.py
in the same directory:
# module.py
def hello(name):
print("Hello {}".format(name))
I can import
that module in my hello.py
:
#hello.py
import module
module.hello("World!") # Hello World!
The same can be done in the interpreter:
>>> from module import hello
>>> hello("World!") # Hello World!
Packages
Packages are made up of multiple Python files (or modules), and can even include libraries written in different languages like C or C++. Seeing an __init.py__
file in a folder typically tells you that that folder is a Python package. The __init__.py
doesn't have to contain any code -- sometimes it does -- it just has to be there for Python take that particular folder as a package.
π my_package
|- __init__.py
|- module.py
# __init.py__
from my_package.module import hello
When you import my_package
in your script, the __init__.py
script will be run, giving you access to all of the functions in the package. In this case, it only gives access to the module.hello
function.
