In this example we use two variables, a and b, which are used as part of the if statement to test whether b is greater than a.As a is 33, and b is 200, we know that 200 is greater than 33, and so we print to screen that "b is greater than a".. Indentation. 4. Learn more. There are some differences as far as syntax and their working patterns … Tested on Python 2.6 through 3.6 and PyPy. Here we discuss an introduction, flow chart, syntax, and examples of if else Statement in Python with some sample code. Although its not recommended to use unstructured control flow in the program the keyword goto is not present in python which can be used to jump in a program. All Rights Reserved.

The decision-making process is required when we want to execute code only if a specific condition is satisfied. The pass statement in Python is used when a statement is required syntactically but you do not want any command or code to execute. An else statement contains the block of code that executes if the conditional expression in the if statement resolves to 0 or a FALSE value.

Python If Else Statement Example. 1. I will not go into details of generic ternary operator as this is used across Python for loops and control flow statements. The key to thinking in a structured way is to understand how and why you are branching on code. Loops in Python. The continue statement can be used in both while and for loops. The following example illustrates the combination of an else statement with a for statement that searches for prime numbers If the variable num is equal to -1, test expression is false and statements inside the body of if are skipped.. An else statement contains a block of code that executes if the conditional expression in the if statement resolves to 0 or a FALSE value..

The conditional if..elif..else statement is used in the Python programming language for decision making. Syntax Gotos are universally reviled in computer science and programming as they lead to very unstructured code. The body of if is executed only if this evaluates to True.. The single if statement is used to execute the specific block of code if the condition evaluates to true. It executes a set of statements conditionally, based on the value of a logical expression.
