Class 8 Python Decision Making - If-Else-Elif
Python Decision Making Statements: If-Else-Elif and Logical and Relational Operators Explained
In this video, we delve into the implementation of decision-making statements in Python. We start with an understanding of why decision-making is essential, drawing parallels to everyday scenarios.
The video explains the basics of `if` statements, focusing on how certain conditions trigger different sets of instructions. You'll learn about relational operators such as `==`, `!=`, ≤, ≥, etc. and see them in action through practical examples.
I will demonstrate simple programs on IDLE app to check for passing marks, identify even or odd numbers, and validate age criteria. The session covers nested `if` statements and introduces `elif` for handling multiple conditions.
Additionally, we discuss logical operators `and`, `or` and common programming errors to avoid. To solidify your understanding, two practice problems are provided:
1. A store gives discount if the person is a child (≤10) or a senior (≥60) and they live in Bokaro. Write a program to implement this rule.
2. Find the largest of three given numbers in two different ways. (Logic is same but the way you implement can be different.)
Stay tuned for the next video where we will explore loops in Python.
