Python If Then Else Example

Example of using if-else ladder in Python z 1000 if z 100 print'z is 100' elif z 200 print'z is 200' elif z 300 print'z is 300' elif z 1000 print'z is 1000' else print'z is unknown' Ever since then, I've been learning programming and immersing myself in technology. On this site, I share everything that I've

and looped if-else statements in the form of for-else and while-else We'll talk about all of these, and also explain the extremely useful double-equals operator. How do you write an if-else statement in Python? If you're just looking for an example to copy-paste, here is a super simple if-else statement in Python

Flow Chart of if-else Statement in Python. Below is the flowchart by which we can understand how to use if-else statement in Python Example 1 Handling Conditional Scenarios with if-else. In this example, the code assigns the value 3 to variable x and uses an if..else statement to check if x is equal to 4.

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 quotb is greater than aquot. Indentation. Python relies on indentation whitespace at the beginning of a line to define scope in

In computer programming, the if statement is a conditional statement. It is used to execute a block of code only when a specific condition is met. For example, Suppose we need to assign different grades to students based on their scores.

In the form shown above ltexprgt is an expression evaluated in a Boolean context, as discussed in the section on Logical Operators in the Operators and Expressions in Python tutorial. ltstatementgt is a valid Python statement, which must be indented. You will see why very soon. If ltexprgt is true evaluates to a value that is quottruthyquot, then ltstatementgt is executed.

Let's look at an example. else statement x 3 y 10 if x gt y printquotx is greater than y.quot else printquotx is smaller than y.quot x is smaller than y. Output x is smaller than y. Here, Python first executes the if condition and checks if it's True. Since 3 is not greater than 10, the condition isn't met, so we don't print out quotx is

After completing the if statement, Python continues execution of the program. The if statement ends by its indetion, it goes back four spaces. Visual example of if statement click to enlarge If-Else. You can use if statements to make an interactive program. Copy the program below and run it.

Learn about various decision making statements in Python like if statement, if else statement, elif ladder and nested if else with examples. If the condition is not satisfied then it skips the execution of the body and executes the further code, if any. The syntax is If expression statement1 statement2 . . .

In the above example, the elif conditions are applied after the if condition. Python will evalute the if condition and if it evaluates to False then it will evalute the elif blocks and execute the elif block whose expression evaluates to True.If multiple elif conditions become True, then the first elif block will be executed.. The following example demonstrates if, elif, and else conditions.
