Python's colon is not for the sake of the compiler (you could theoretically parse a version of Python without them), there were studies that showed that it's easier for humans to read with it than without. A lot of Python's design decisions were made because it's easier for humans to read and write (keyword operators, whitespace syntax, explicit return).
