Python variables are used to store data values. They act as labels for data, allowing you to reference and manipulate that data throughout your program. Here are some key points:
- Assignment: You create a variable by assigning a value using the
=operator. For example,x = 10assigns the value10to the variablex. - Dynamic Typing: Python is dynamically typed, meaning you don't need to declare the variable type explicitly. The type is determined at runtime based on the assigned value.
- Naming: Variable names can include letters, numbers, and underscores, but must start with a letter or underscore. They are case-sensitive (e.g.,
myVarandmyvarare different). - Scope: Variables can have different scopes (local, global) depending on where they are defined.
Here's a simple example:
name = "Alice" # String variable
age = 30 # Integer variable
