Part 1 **********************************************************

In Python, a variable is a way to store data so you can use it later. Variables can hold different types of data:

1. integer

x = 5

1. Float “Decimal numbers”

x = 3.5

1. string (Characters enclosed in quotes) A string can contain letters, numbers, and symbols, and it's created by enclosing characters in either single or double quotes. For example:

name = “soda”

1. Concatenation

You can combine (concatenate) strings using the + operator. Here’s an example:

greeting = "Hello"
name = "Clarissa"
full_greeting = greeting + " " + name  # Combining strings with a space in between
print(full_greeting)

Python supports basic arithmetic operations like addition (+), subtraction (-

), multiplication (*), division (/), and exponentiation (**).

• a = 10
• b = 3
• result = a + b # Addition
• difference = a - b # Subtraction
