👋 What's shaking, bacon? This is the first content of Python Basics module. This module does not have the goal to teeach you everything in Python, but to give you a glimpse of how the programming language works and to give you the basic knowledge to kick off your big adventure in Python. So, let's go!
 
In this first class, we are going to learn how to declare variables and constants, what are the basics data types and operations, and how to input and output datas.
 
Oh, and you can get all the material in this GitHub Repo: python-basics-posts.
 
 

0) Declaring Variables and Constants! Basic Data Types!!

 
Python has five basics data types: string, integer, float, boolean and complex number.
Besides, you can declare variables using the = operator, and encapsule the data by parenthesis () to transform a variable to a constant.
 
#
# ---- Variables ----
#
my_string = "Hello World!"
my_integer = 42
my_float = 42.0
my_boolean = True # or False
my_complex_number = 4 + 2j # yeah, you have to use 'j' instead of 'i'

#
# ---- Constants ----
#
MY_STRING_CONST = ("Hello World!")
MY_INTEGER_CONST = (42)
MY_FLOAT_CONST = (42.0)
MY_BOOLEAN_CONST = (False)
MY_COMPLEX_NUMBER_CONST = (4 + 2j)
 
 

1) Basic Operators

 
Now, let's learn about the math, boolean and bitwises operators.
 
#
# ---- Math Operators ----
#
addition = 2 + 2
subtraction = 4 - 5
multiplication = 8 * 5
division = 4 / 2

quocient = 3 // 2
power = 2 ** 5
modulus = 5 % 3

#
# ---- Boolean Operators ----
#
True and False
True or False
not True;

#
# ---- Bitwise Operators ----
#
and_bitwise = 5 & 2
or_bitwise = 5 | 2
xor_bitwise = 5 ^ 2
right_shift_bitwise = 5 << 2
left_shift_bitwise = 5 >> 2
 
 

2) Input and Output

 
For input, we are going to use input built-in function, and for output, guess what! We are not going to use output built-in function, because this one does not exist! We are gonna use print instead!
 
#
# ---- Input ----
#
my_input = input("Type anything:")

#
# ---- Output ----
#
print(f"My Input: {my_input}")
 
 
Well, hope you enjoyed this quick guide, and see you on the next one, where we will be learning about more complex data types, such as lists, dictionaries and tuples.
 
See ya! 👋
