# Operators

## Selection Operators

When we are comparing two values like in an if statement there are a number of operators than can be used: In the example below the print line will only be executed if the temperature value is above 25: If we entered 25 exactly then the print line beneath it would not run because technically it is not above 25. We could use the greater than or equal to sign ( >= ) as in this case it would run the print line if you entered 25 because it is greater than or equal to 25: You can use the less than ( < ) and less than or equal to sign ( <= ) in a similar way (and implement an elif at the same time): Now there’s only one thing missing from this program – we need an else statement for any value that is inputted between: Can you work out which sentence would be printed if we entered 8, 10 and 24?

The opposite of equal to (==) is not equal to (!=); for example: Practice Task 1
