How does this "if" syntax works?

When Kenneth used the os library, he wrote:

"cls" if os.name == "nt" else "clear"

I've never seen this syntax for an if statement. I would expect the if keyword to be the very first thing, as usual. Anybody got any info about this?

Thank you,

This isn't actually an "if" statement, though it does have the term "if" in it.

This is a "conditional expression". If you are familiar with other languages, you may have run into something called a "ternary". This is the Python equivalent.

For more info see the Python Documentation.
