Hello guys!

Welcome to another @CoolJames1610 tutorial :P :P :P

Now, I am going to teach you how to PYTHON the COOLJAMES way (which is cool)

Lesson 1 - Sequences

So, the first lesson will be about sequences.
But first let's go over some key terms.

• Declaring variables.
  Unlike other PL's, in Python you do not need to add BOOL, or STR, or INT before you declare a variable. Python automatically knows which data type you enter in.
  Example:

x = 0 #Integer
x = "Hey" #String
x = True #Boolean

• Artithmetic
  Arithmetic is mainly the same across PL's.

x = 5 + 5
y = x + 10
z = x * y

• Keywords
  These are a few of the keywords in Python. You cannot declare these variables

import
from
as
and
not
in
print

etc... I can't remember all xD

Okay, I think that is all for the basics, now onto sequences...

A sequence is just commands all after each other

Example

print("Hello World")
x = "James"
print("Hello " + x)

So in this program, Python will output 'Hello World', then assign '"James"' to x and then out put 'Hello" added with the value attached to x

Python is quite simple xD

Now let's move onto input from the user.
All you have to do to get input from the user is:

x = input()

This will prompt your user to enter something.
Now this wouldn't be very helpful as nothing is telling the user to input something.
We can add text to the input

x = input("Please enter your name: ")

As you can see, I have left a space after the colon. This is better to do as the program will look neater.
This:

Please enter your name: James
or
Please enter your name James

Instead of:

Please enter your name:James
or
Please enter your nameJames

See? :D Much neater :P

I'm tired of people not adding a space or something lol

Okay now, I'll talk briefly about concatenation.
This is combining different data types together.
Say I asked the user for their age and I wanted to say: "Oh nice, I am also " (user's age), most people may just do:

x = input("Please enter your age: ")
print("Oh nice, I am also " + x)

Here we would get an error.

In Python, if you are outputting to the screen, everything has to be the same data type.

"Oh nice, I am also" is a string
x is an integer.

To get round this problem, we can cast x to a string so that we can use it to say something.
All we need to do is str(x). This changes x to a string and can be used.

x = input("Please enter your age: ")
print("Oh nice, I am also " + str(x))

Ahaha no error ;)

We can cast a string to an integer but only if it is a whole number (e.g. not a decimal)

x = "10"
e = 34 * int(x)
print(e)

Here, x is a whole number so we can cast it as an integer.
(Would output 340 in case you wanted it :P)

There are also the bool and float casters.

I think that is it for today's tutorial

I know this isn't good and not in depth but I DON'T CARE xD

This is how I kinda learnt Python and I've learnt a lot xD

Erm, please upvote so that amasd can comment again people can see and learn :)

Lesson 2 will be about Selection (if, elif, else)

Thanks again,
@CoolJames1610

IM GETTING BETTER AT MARKDOWN EEEEEK
