It works the same as a unary minus. Python is a common-goal high-stage programming language and is widely used among the developers’ group. Python was mainly developed for emphasis on code readability, and its syntax permits programmers to specific ideas in fewer lines of code. If you are new to programming and need to study Python Programming from Scratch, then this complete 2024 Python course guide is here that will help you.
