#Python has several Easter eggs built in! 🐍πŸ₯šπŸ£πŸ‡

An Easter egg is a fun little surprise in a programming language, video game or movie.

Let's talk about some of Python's cool Easter eggs!

πŸ§΅πŸπŸ‘‡
πŸ₯š1️⃣ - The most famous #Python Easter egg is probably The Zen of Python, which you will see if you "import this"
πŸ₯š2️⃣ - What you might not know is that Zen of Python's source is really interesting too:

github.com/python/cpython…
πŸ₯š3️⃣ - The next most well-known Easter egg in #Python is probably "import antigravity"

If you type that in your Python REPL, you will be taken to this XKCD comic: xkcd.com/353/
πŸ₯š4️⃣ - Create "Hello World" with an import in #Python!
πŸ₯š5️⃣ - Let's try and import braces in #Python!

Nope! That Easter Egg won't let us!
πŸ₯š6️⃣ - This Easter Egg is kind of tricky. It's for the math nerds in #Python

If you hash infinity in Python, you get back a representation of Pi

If you hash NAN, you will get zero
πŸ₯š7️⃣ - Barry Warsaw, a longtime #Python core developer, was nominated "Friendly Language Uncle For Life" or FLUFL

If you do this special import, the inequality operator "!=" is replaced with "<>"
There are a few other Easter eggs mentioned in this curated list of Easter Eggs in Python on GitHub:

Did you know that #Python supports SQLite in the standard library? That's right. You don't need to install anything! πŸπŸš€

Let's talk a little about that!

πŸ§΅πŸ‘‡
If you have a pre-existing SQLite database file, you can use #Python's `sqlite3` module to connect to it

Here's how: Image
If you want to create a new SQLite database with #Python, you can use the same syntax that you'd use to connect to a pre-existing one.

Then create a cursor object and create your table, like this: Image

Today is a great day to talk about #Python lambdas!

Let's learn about them in a thread

πŸπŸ§΅πŸ‘‡
A Python lambda is a one-line anonymous function.

Rule #1 is do NOT assign a lambda to a variable.

When you do that, it's no longer an anonymous function. You should just create a regular function at that point Image
If you want to run a lambda in your REPL, wrap it in parentheses, like this: Image

Want to create a copy of a #Python list? Use Python's `copy()` method!

Note: Watch out if your list contains lists of dictionaries. In those cases, you might be better off using copy.deepcopy()
But be careful! If your list contains a mutable object, like another list or a dictionary, you may encounter some unexpected behavior.

In the following example, you `copy()` the list. Then you modify the nested dictionary in the copy, but that also changes the original list!
You can fix this behavior by using Python's `copy` module. It provides a deepcopy() function that you can use which will make a deep copy of the ENTIRE list!

#Python generators aren't talked about enough.

So let's talk about them today!

πŸ§΅πŸπŸ‘‡
According to the #Python wiki, "Generator functions allow you to declare a function that behaves like an iterator"

One of their best use cases is to chunk through large data sets a piece at a time, which prevents you from running out of memory.

wiki.python.org/moin/Generators
To create a generator in #Python, you need to use the `yield` keyword instead of `return` inside a function.

Generators will continue to yield values until the generator is exhausted.

The following example will continue to yield numbers for as long as you call it: Image

Starting in Python 3.7, the `breakpoint()` built-in function was added

It is defined in PEP 553 and simplifies adding a breakpoint to your code
