I have learned how to define the future function in a program and reuse code. If you want to reuse many functions in other programs, you need to use the module. The module is basically a file that contains all defined functions and variables. To reuse a module in other programs, the file name of the module must be. py. The module can be input from other programs to take advantage of its functions. This is also the method for using the python standard

Memory management of language is an important aspect of language design. It is an important factor in determining language performance. Whether it is the manual management of C language or the garbage collection of Java, it becomes the most important feature of language. In this example, the Python language illustrates a dynamic type, object-oriented language memory management method.memory usage of the objectAssignment statements are the most common

... One of the most important advantages of Python 2 is that it has a large number of third-party libraries that can be used to do anything, but Python 3 doesn't have that advantage.
