Before we start, I need to explain the concept of "Package". Calling the "package" to "package" is my habit, if you feel my teaching is wrong, welcome to message me, very thanks. Because in the field of programming, I am just a little rookie.

Python has many kinds of data types, so it's hard to me to give examples of all of them.

So, I introduce the data type we use in Python by simple today.

"Tuple", as similar as List. We can store the different data type value in them. But tuple we can't add, remove, update our value in tuple.

"List", is a most commonly used data type in Python. Of course, if you are learning Machine Learning. (The most commonly used data type probably is Numpy.)

If you are used to reading tutorial of Python official, maybe you can refer to this website.

I want to share with you how to use a important feature "lambda" today.

This is a feature that I didn't use often. After all, I am too lazy, haha.

I always feel that I can use "def" directly XD (This is not a good habit

The previous tutorial teach how to create a basically function. Today I note a skill I rarely to use, the value we will give function: default, *args, **kwargs.

The explanation part will a bit in my way, I guess you go trying more different code, don't care about my nonsense. Hahahahaha.

The "function" is part of the programming language structure.

I think we can simply define it as "program components that can be called multiple times after being packaged."

The previous we mentioned the "bool", and we simply teach the basically concept of "True" and "False".

If my tutorial have wrong content, please leave me a message below to let me know, thank you =)

I don't care I'm corrected, but I care I mislead anyone.

If we want to discuss the "True" and "False" in Python, we must mention a data type —— "Boolean".

Boolean is also know "Bool", which is the "Boolean value" that you maybe often see in books on programming language.

In the program, the simplest bool value is "True" or "False", that is "1" or "0", it is just that simple.

before we teaching the concepts of "break", "pass", "continue" ......, I think I have to complete the lack of "while-loop".

The "while", we can think of it as a "loop that continues to execute as long as it meets the conditions."
