What is Variables in Python | EP-4 Python Variables Tutorials | How to Create Variables in Python
In Python, a variable acts like a container that stores data values. These values can be anything from numbers and text to more complex data structures like lists or dictionaries.
Here are some key points about variables in Python:
Creating a Variable: Unlike some other programming languages, Python doesn't require you to declare a variable before using it. You create a variable simply by assigning a value to it using the equal sign (=).
Data Types: Each value in Python has a data type, which specifies the kind of data it is. Common data types include integers, floats, strings, booleans, and more. Variables can store different data types throughout a program.
Reassigning Values: The value stored in a variable can be changed later in your code. This makes variables flexible for calculations and keeping track of changing information.
Naming Conventions: When choosing names for your variables, you should follow a few conventions:
Variable names can start with letters (a-z, A-Z) or underscores (_).
They can only contain letters, numbers, and underscores.
Python is case-sensitive, so name and Name are considered different variables.
