00:00https://realpython.com/lessons/creating-python-packages/#t=0.745
Let’s create a package structure.https://realpython.com/lessons/creating-python-packages/#t=0.745
I’m here in my terminal,https://realpython.com/lessons/creating-python-packages/#t=2.537
but you can totally create those files in your Windows Explorer or yourhttps://realpython.com/lessons/creating-python-packages/#t=4.035
Mac Finder or on your Linux file applicationhttps://realpython.com/lessons/creating-python-packages/#t=8.955
app, which name I don’t know,https://realpython.com/lessons/creating-python-packages/#t=14.035
but you can also follow me along with the terminal.https://realpython.com/lessons/creating-python-packages/#t=16.075
00:20https://realpython.com/lessons/creating-python-packages/#t=20.855
Navigate to the desktop and create a folder namedhttps://realpython.com/lessons/creating-python-packages/#t=20.855
packages_example/.https://realpython.com/lessons/creating-python-packages/#t=25.925
Then navigate into this folder.https://realpython.com/lessons/creating-python-packages/#t=27.71
00:34https://realpython.com/lessons/creating-python-packages/#t=34.375
And in this folder, create another folder.https://realpython.com/lessons/creating-python-packages/#t=34.375
And this one,https://realpython.com/lessons/creating-python-packages/#t=37.106
you name mypackage/.https://realpython.com/lessons/creating-python-packages/#t=38.375
00:43https://realpython.com/lessons/creating-python-packages/#t=43.295
The packages_example folder is called the project folder,https://realpython.com/lessons/creating-python-packages/#t=43.295
or project root folder,https://realpython.com/lessons/creating-python-packages/#t=48.095
because it will contain all the files and folders in thehttps://realpython.com/lessons/creating-python-packages/#t=49.905
packages_example/ project.https://realpython.com/lessons/creating-python-packages/#t=53.395
00:55https://realpython.com/lessons/creating-python-packages/#t=55.135
The mypackage/ folder will eventually become a Python package.https://realpython.com/lessons/creating-python-packages/#t=55.135
It isn’t one right now because it doesn’t contain any modules.https://realpython.com/lessons/creating-python-packages/#t=59.495
So to change that, hop over to IDLE and create a new editor window.https://realpython.com/lessons/creating-python-packages/#t=63.455
01:10https://realpython.com/lessons/creating-python-packages/#t=70.005
As mentioned before, to make a folder a Python package,https://realpython.com/lessons/creating-python-packages/#t=70.005
you need to have a __init__ file in it.https://realpython.com/lessons/creating-python-packages/#t=73.125
So never forget to have __init__ in it.https://realpython.com/lessons/creating-python-packages/#t=75.925
01:20https://realpython.com/lessons/creating-python-packages/#t=80.192
Yeah,https://realpython.com/lessons/creating-python-packages/#t=80.192
and as mentioned before, also this file can be empty.https://realpython.com/lessons/creating-python-packages/#t=81.215
So without adding any content to it,https://realpython.com/lessons/creating-python-packages/#t=84.815
save a new file from your IDLE editor window ashttps://realpython.com/lessons/creating-python-packages/#t=87.665
__init__.pyhttps://realpython.com/lessons/creating-python-packages/#t=92.605
in the mypackage/ subfolder of your packages_example/ folderhttps://realpython.com/lessons/creating-python-packages/#t=95.615
01:44https://realpython.com/lessons/creating-python-packages/#t=104.355
Then open another window and add the following function:https://realpython.com/lessons/creating-python-packages/#t=104.355
def greet(name):https://realpython.com/lessons/creating-python-packages/#t=108.765
And then on the next line,https://realpython.com/lessons/creating-python-packages/#t=112.845
indented, print().https://realpython.com/lessons/creating-python-packages/#t=116.855
And then let’s do an f-string: f"Hello, {name}!" and the closing parentheses.https://realpython.com/lessons/creating-python-packages/#t=119.335
02:12https://realpython.com/lessons/creating-python-packages/#t=132.155
So there is a greet() function that takes name, and insidehttps://realpython.com/lessons/creating-python-packages/#t=132.155
greet(),https://realpython.com/lessons/creating-python-packages/#t=136.865
you call the print() function, and then you print a string, Hello, with thehttps://realpython.com/lessons/creating-python-packages/#t=137.435
name that was passed into the function.https://realpython.com/lessons/creating-python-packages/#t=142.295
02:25https://realpython.com/lessons/creating-python-packages/#t=145.435
Save this file as module1.pyhttps://realpython.com/lessons/creating-python-packages/#t=145.435
in the same folder as the __init__ file.https://realpython.com/lessons/creating-python-packages/#t=147.685
And to make the package complete,https://realpython.com/lessons/creating-python-packages/#t=153.305
create a new file in your IDLE editor with this code—https://realpython.com/lessons/creating-python-packages/#t=155.345
def depart():—which takes one parameter,https://realpython.com/lessons/creating-python-packages/#t=160.855
which is name.https://realpython.com/lessons/creating-python-packages/#t=163.725
02:45https://realpython.com/lessons/creating-python-packages/#t=165.514
And inside the function body, againhttps://realpython.com/lessons/creating-python-packages/#t=165.514
a print() function call.https://realpython.com/lessons/creating-python-packages/#t=168.575
And this time, you use an f-string saying goodbye,https://realpython.com/lessons/creating-python-packages/#t=169.835
and then in curly braces the name.https://realpython.com/lessons/creating-python-packages/#t=174.115
02:59https://realpython.com/lessons/creating-python-packages/#t=179.595
Just like before, you’ll save this file in the mypackage/ subfolder.https://realpython.com/lessons/creating-python-packages/#t=179.595
And you name this file module2.py,https://realpython.com/lessons/creating-python-packages/#t=183.185
03:11https://realpython.com/lessons/creating-python-packages/#t=191.055
and that’s a package.https://realpython.com/lessons/creating-python-packages/#t=191.055
With this structure, the files, and the code in place,https://realpython.com/lessons/creating-python-packages/#t=192.466
you are now ready to import and use these modules in another module.https://realpython.com/lessons/creating-python-packages/#t=196.375
