Simple Python Code With Branch Examples

The best way to learn Python is by practicing examples. This page contains examples on basic concepts of Python. We encourage you to try these examples on your own before looking at the solution. All the programs on this page are tested and should work on all platforms. Want to learn Python by writing code yourself?

For example, in a PassFail class, if a student's score is greater than or equal to 60 point, the grade is Pass, otherwise, the grade is Fail. The two-branch decision can be depicted using the following flow chart The if-else Syntax You can code the two-branch decision using the if-else statement that has the following syntax

For example, if the input argument is odd, you may want the function to perform one operation on it, and another if the input argument is even. This effect can be achieved in Python using branching statements i.e., the execution of the function branches under certain conditions, which are the topic of this chapter.

If condition_1 is True, Python executes do A. Otherwise, Python proceeds to check condition_2 in the elif part. If condition_2 is true, Python executes do B. Otherwise, Python executes do C. The else part is called a catch-all, and it is the default decision when all the checking conditions fail. Ex redo the weather example above

A block of code to execute If the test is True An optional block of code to execute if the test is False Table of Contents . A simple example of if and else in Python Nested if, else and elif in Python Compound conditions inside if Such a desire can be achieved using if else clauses in Python. A simple example of if and else in Python

Our Python code will execute the first, second, and so on. On the fourth instruction, we have specified a condition. So, the program will only execute the fourth instruction if the statement is true. If not, it will bypass the fourth instruction and move on to the fifth. Let's take a look at an example of this concept using a code snippet.

This code is a simple program that asks you to enter a password if you enter the correct password, 'qwerty', it displays 'Welcome'. Branching using If Else in Python. After if, the next conditional branch control you need to learn is 'else'. This command is a companion to if and runs as an alternative version. When the if

Now, I will teach you various examples and different methods of Decision-making. Let's start, The below diagram clearly understanding Control Structures or Decision-making processes. Now we will see the branching Statements types. if condition. This statement is used to test the condition only. Syntax. Flow Chart. A simple method of if statement

Python provides three branching statements break, continue and return. In Python pass also a branching statement, but it is a null statement. Branching statements in Python are used to change the normal flow of execution based on some condition. The return branching statement is used to explicitly return from a method.
