Python functions and modules, Python function modulesIntroduction Function concepts also exist in python. Standard functions can be called built-in functions, which can be called directly by function names. However, some other built-in functions

IntroductionIn Python there is also the concept of functions, the standard function we can call built-in functions, such functions can be directly called through the function name. But there are other functions that are not built-in that cannot be

5.1 Number typesThe numbers provide scalar storage and direct access. It is a non-changeable type, meaning that the value of the change number generates a new object. Of course, this process is transparent to both the programmer and the user, and
