The aifc module in #Python will be deprecated in Python 3.11

But it's still worth knowing about because so many people will still be able to use it.

This module provides support for reading and writing AIFF and AIFF-C files

docs.python.org/3/library/aifc…

#PythonStdLib 🐍🔥

🧵👇
AIFF is Audio Interchange File Format, a format for storing digital audio samples in a file. AIFF-C is a newer version of the format that includes the ability to compress audio data.

You can read and write these files with #Python using the aifc module!
When you go create an AIFF file with #Python, you use much the same type of code as you would when you use Python's `wav` module.

Here's an example:
Need to read an AIFF file with #Python? 🐍🔥

Here's one way to do it:
Thanks for reading my mini-thread on reading and writing AIFF files with #Python

Module number 3️⃣ on our #Python standard lib tour is `argparse`

The argparse module makes it easy to write user-friendly command-line interfaces.

#PythonStdLib 🐍🔥

🧵👇
Here is an example of creating an argument parser with no arguments.

Why would you do that? Well, to find out what `argparse` gives you out of the box 📦!

You can see here that `argparse` gives you some help text and prints out your provided description Image
A common coding pattern for argument parsing is to put the argument parsing code into its own function or method and then return the parsed args.

Here's an example: Image

#Python comes with lots of modules. Let's get started by looking at the `abc` module.

The `abc` module isn't for learning the alphabet! It's for creating Abstract Base Classes 🤯!

Let's learn more about those now 🧵👇

#PythonStdLib 🐍🔥
Abstract base classes (ABCs) are defined in PEP 1139.

You can read all about them here:

python.org/dev/peps/pep-3…
Abstract Base Classes in #Python provide the following:

🐍 A way to overload isinstance() and issubclass().
🐍 A new module abc which serves as an “ABC support framework”.
🐍 Specific ABCs for containers and iterators, to be added to the collections module.

Did you know #Python has a `weakref` library built-in? 🐍🔥

Python won't delete an object until all its references are deleted. A weak reference does not protect you from garbage collection.

Join me for a short mini-thread!

🧵👇
Let's look at an example of #Python code that has two references to the same object

In this example, to be able to delete the object, you must delete both variables, "a" and "b": Image
Now let's use Python's `weakref` library to make the second reference into a weak reference

You'll note that now when you go to delete the original reference, the weak reference is also removed. Image

#Python has TONS of great packages and frameworks.

In this thread, I am going to highlight just a few of the THOUSANDS that are available to you on pypi.org

🐍🧵👇
Python has lots of great cross-platform GUI packages:

🐍 PySimpleGUI @PySimpleGUI
🐍 PyQt / PySide
🐍 wxPython
🐍 Tkinter
🐍 @DearPyGui
🐍 EasyGUI
@PySimpleGUI @DearPyGui #Python also has a couple of GUI frameworks for mobile development (i.e. iOS and Android):

🔥 Kivy @kivyframework
🐍 Toga from @PyBeeWare

I have heard PyQt also supports mobile, but haven't been able to verify it

Have you used #Python's `enum` module yet? No?

Then you should check out today's mini-thread!

🐍🔥🧵👇
Enum is short for enumerations which is a set of symbolic names (members) bound to unique, constant values.

Do NOT confuse the `enum` module with the `enumerate()` function though. 🐍⚠️

For full details on the `enum` module, see the docs:

docs.python.org/3/library/enum…
Let's look at an example of using the `enum` module.

In the following example, you subclass `enum.Enum`.

Then you add some enum values as class attributes, kind of like how you would with a dataclass

The `Enum` class supports iteration, so you iterate over it at the end

#Python strings have TWELVE methods for testing string contents:

🐍 isalnum()
🐍 isalpha()
🐍 isascii()
🐍 isdecimal()
🐍 isdigit()
🐍 isidentifier()
🐍 islower()
🐍 isnumeric()
🐍 isprintable()
🐍 isspace()
🐍 istitle()
🐍 isupper()

🧵👇
Let's get started learning about these methods by looking at ` isalnum()`, which returns True if all characters in the string are alphanumeric and there is at least one character,
The `isalpha()` string method will return True if all characters in the string are alphabetic and there is at least one character
