Don't expect to make AAA games or state of the art machine learning models in a week.

With all that being said, let's dive straight in.

Linux and macOS users can skip this step because they come pre-installed with Python.

- Printing statements
- Variables
- Operators
- Conditions
- Functions
- Loops
Let's take a closer look.

You can 'print' or output in Python using the print() function.
print('Hello World') will give you an output of `Hello World`
(10 / 24)
These store certain values that can change.
For example, You can declare a variable 'x' with a certain value.
x = 9 [Here 9 is assigned to varaiable x]
y = 'Hello World' ['Hello World' is assigned to y]
x = 8 [x has been updated to a new value which is 8]

These carry out arithmetic operations in Python
+ : Addition
- : Subtraction
* : Multiplication
/ : Divide
% : Modulus (Remainder after dividing)
** : Exponents
(12 / 24)
They look like this 👇
a = 33
b = 200
if b > a:
print("b is greater than a")
else:
pass
Think of it as telling Python to do something based on conditions: if this is true, do this; else do something different.

These are basically blocks of code that can be run when you call them. This helps us write code more efficiently.
In Python, you can make functions using the def keyword.
def myFunction():
print("Hello")
myFunction()
(14 / 24)
These essentially run a piece of code over and over again until a certain condition is met.
There are 2 types of loops in Python:
- While loops
- For loops
Let's take a look at them.

i = 1
while i < 6: //While i is less than 6
print(i) // do
i += 1 //this
The output is :

fruits = ["apple", "banana", "cherry"]
for fruit in fruits:
print(x)
The output:
(17 / 24)
'fruit' is the above loop is a temporary variable. It gets a value from the list called 'fruits' starting from "apple" then to "banana" and then "cherry".
