• This video teaches you how to install python
• The installation may vary depending on your computers operating system, follow the approriate links for installation:
• https://www.python.org/downloads/
• Once python is installed it is recommended you install a IDE (Integrated Developer Environment) to run the code
• The second video will explain how to install VSCode, a popular IDE. You can also install others like PyCharm depending on your preference.

Variables

• Variables:
• A variable is a way to store data so that it can be referenced or used in some way in a program
• Here is an example of storing different types of data in variables and printing them:

Operators

Operators allow for manipulation & comparison

• Using the variables we made previously, we can use python operators to manipulate the data
• This chart shows the operators available in Python

Loops

There are two types of loops in python, a for loop and a while loop

For Loops:

While Loops:

While loops in python execute code as long as the initial condition is satisfied, as the image below demonstrates

For loops are typically used to sequentially iterate over a rnage or over a list.

Strings

• Strings in python are designated by anything in single (' ') or double (" ") quotes.
• The individual characters of a string can also be accessed by using bracket notation [ ]

Lists

• You can add to lists by using the append function as so:

• Lists are a common data structure in Python that can grow or shrink depending on how many elements are inside them
• They are notated by elements inside the square brackets: "[ ]"
• Here is an example of creating and accessing elements in a list
