expression evaluation in python with example

Expressions in Python are combinations of values and operators that can be evaluated to produce a result. Understanding how expressions are evaluated is fundamental to writing effective Python code. In this tutorial, we'll explore the basics of expression evaluation in Python, covering operators, precedence, and examples.
Python supports a variety of operators for performing different operations on values. Some common operators include:
Operator precedence determines the order in which operators are evaluated when an expression contains multiple operators. For example, multiplication has a higher precedence than addition. Parentheses can be used to override the default precedence.
Here's a brief overview of operator precedence (from highest to lowest):
Let's go through a simple example to illustrate expression evaluation in Python. Consider the following expression:
To evaluate this expression, follow the operator precedence rules:
So, result will be assigned the value 9.
When you run this code, you should see the output:
Feel free to experiment with different expressions to gain a better understanding of expression evaluation in Python. Remember to use parentheses to control the order of operations when needed.
