break may only occur syntactically nested in a for or while loop, but not nested in a function or class definition within that loop.

Can Break be used in if statement?

break will not break out of an if clause, but the nearest loop or switch clause. Also, an if clause is not called a “loop” because it never repeats its contents. The break statement has no use in decison making statements. … The if statement is not a loop .
