Python is an incredibly versatile programming language known for its simplicity and readability. Two fundamental concepts of any programming language are variables and operators. Understanding these concepts will help you write cleaner, more efficient code. Let’s dive into Python variables and operators!

Variables

In Python, variables are used to store values such as numbers, strings, lists, dictionaries, or even other objects. They act like containers where data can be stored temporarily during program execution. To declare a variable, simply assign a value to it using the = sign.

For example:

name = "John Doe" 
age = 35 
height_cm = 178.5 
is_student = False

You don't need to specify what type of data a variable should hold; this flexibility makes Python dynamic and easy to learn. You may change a variable's content at any time:

name = "Jane Doe" 
print(name) # Output: Jane Doe

Operators

Now let’s move on to operators — symbols representing actions taken on one or two operands. There are several types…
