For the creation of libraries you have to write them inside “{}”, and here is a little example:
This is my own dictionary, you just have to assign integers to your library.
That’s all for my semestre with Ken, may Harambe be with you

There are two ways in which you can use ranges in python:
1st. You’ll just simply write
x = range(10)
print(x)
And it will print all number that goes from 0 to 10.
2nd. You write almost the same thing but:
x = range(0,10,2)
print(x)
This means that the range for x will start in 0, it will end at 10, and its frequency it is of 2.
And it is easy as this.
Never forget Harambe, he was not just a gorilla.

This is a very easy topic, we only need 2 things, a file .txt, and to know the “modes” in which you can open/use the file.
These are the ways in which you can use the .txt files:
“r” = To read
“w” = For writing
“a” = For appending
Knowing now this, in your program you’ll just need to write it in this way:

The main points of this topics, it is to use the functions “try”, “except” and “else”, and the propourse of this, is to make our program perfect, meaning that it will no crash. We can the user whatever we want, and as long as he answers right, the program will continue.
This is an example:
Aaaaaand this is basically the key of validating users, if you want to know more about it, you can check this videos out:

A string is a sentence that you’ll use in several times, and it is so easy to use, and you’ll use it everytime you make a program.
This is an example:
And that’s it! When you run the program you’ll get your string

This is a very easy topic and I’ll explain it in a very easy way.
To identify a list and a tuple just look at this example:
A tuple can be write withouth the “[” “]”, and also you can use “(” “)”, so it is the same if you write:
x = 1,2,3,4
or
x = (1,2,3,4)
But for lists you’ll need to write it with “[” “]”
y = [5,6,7,8]
And now, you can use these lists and tuples in several ways, but I’m going to show the easiest way to use them, and we are going to ask for a number in a certain for position, and for this you need to know that python starts counting from 0.

This post will go straight to the point , so watch out, lads.
For getting started, you’ll need first to state a list for “For”
From that list you can print the numbers in it, also whenever you print a number, you can print other Strings, but they have to be inside of it too.
Example:
Besides, you can also print numbers in a range you ask for:
Not only integers, you can also use Strings:

In python 3 we have 5 main basic types, which are: Booleans, numbers, integers, floats and fractions; which I’ll explain:
Booleans: Tells us if something is true or false
Numbers: Like the name say this variable let us save numbers
Integers: Only whole numbers (1,2,3,87108)
Floats: Numbers with decimals (1.1, 1.4831,24384.0053)
Fractions: (½, 412/30)
There are also other types as strings (which are sequences of Unicode characters, or in other words just plain text), lists (It is the most versatile datatype in Python, and like the name says it is a list of data, and this data doesn’t necessarily have to be of the same type.) tuples (tuple is a list, that once it is created it cannot be modified), sets (a set is like an un-ordered bag of unique values) and dictionaries(dictionary is a way to store data just like a list, the difference is that you can use almost everything to search for the data, pretty much like a database which lets you store data and also organize it)

Python 3 have so many libraries that you can use when you need them, and you just need to call for them in your program, and in this post I’ll give an example with “math” because is the easiest one (lol).
To make use of the math library you just need to “call” for it:
So the only to do here is to import the library you want to use, the print whatever you want of the library.
In here you can find all the libraries Python 3 can offer you:
https://docs.python.org/3/library/
To create your own library, you need to make another file where you are going to create a function.
Now that you have this function, you’ll import it to another file where it is going to run with the number you assign to x.
And now you made two mastery topics in one!
