Use to subtracts the second worth from the primary worth and offers the distinction between them. It really works the identical as a unary minus. Python is a general-goal excessive-degree programming language and is widely used among the many developers’ neighborhood. Python was primarily developed for emphasis on code readability, and its syntax permits programmers to express concepts in fewer strains of code.
