Python Variables
Variables in Python are containers for storing data values. Here are some key aspects of Python variables:
In Python, you don't need to declare variables explicitly. They are created when you first assign a value to them.
x = 5
y = "Hello"
Variable names must start with a letter or underscore, can contain letters, numbers, and underscores, and are case-sensitive.
my_variable = 10
_private = "This is private"
camelCase = "Different from CamelCase"
Python allows you to assign values to multiple variables in one line.
a, b, c = 5, 3.2, "Hello"
Python is dynamically typed, meaning you don't need to specify the type of a variable. The type is inferred based on the assigned value.
x = 5 # x is now an integer
x = "John" # x is now a string
