What is an If-Elif-Else statement?

If-Elif-Else allows your code to split in response to what the user chooses to do. For example,  you can use If-Else to code a simple yes or no question and based on the user choice, either the Yes code will be followed or the No code will be followed. However, with If-Elif-Else you can create conditions with more than just two answers.

Python challenge - If-Elif-Else statement

​Enter the following code in a Python code editor. Before running the code, what do you think it will do?. Press "F5" then "Enter" to run
Explanation:
The first line asks a user to enter an integer to answer the question. This number is then held within the variable called "litter". This value is then compared to the numbers pre-defined numbers in the "if" and "Elif" statements. If the number meets a condition, then that branch of the code is executed.

Relational operators

In the example code above, two different relational operators are used, == and <=. Below is a list of relational operators that can be used in your code
Relational operator
Description
==
If the values of two operands are equal, then the condition becomes true.
!=
If values of two operands are not equal, then condition becomes true.
>
If the value of left operand is greater than the value of right operand, then condition becomes true.
<
If the value of left operand is less than the value of right operand, then condition becomes true.
>=
If the value of left operand is greater than or equal to the value of right operand, then condition becomes true.
