The control flow statements are required to execute the program to fulfill the condition or requirements. These statements control the flow of execution of a program. There are different types of control statements used in Python and the list is given below,
if, else, and elif.
or loop, range(), and while loop.
break and continue.
In this tutorial, We will learn decision-making statements such as
if, else, and elif.
One of the basic control flow statements is the if statement. It is used to execute a particular condition in the program. Indentation or white spaces maintain is one of the most important parts of Python programming. Any curly braces are not used in Python like other programming languages. In the case of the if statement programmer has to give full attention to the use of indentation.
if (condition) #statement or body
It is an optional statement in the if statement. It is used to execute a false part of any condition. The else statement executes any program at least once whether the condition is false. This statement is used after the if statement. This statement cannot be used without if statement.
if ( condition ): # statement or body else: # statement or body
The elif statement is used in Python to execute multiple conditions in a program. This statement is used after the if statement. The elif statement cannot be used without an if statement. The if statement can be used single in a program but the elif statement cannot be used alone. After if statement more than one elif statement can be used. At the last else statement is used.
