python/module and Package Module 1. What is a module?Module is the py file2. Why use modules?If you encode on the interpreter, the file that was written before the interpreter is closed does not exist, and can be permanently saved to disk if the

A python file is a module that uses a separate namespace, but it is clearly not enough to use modules to define Python functionality in practice. Because a large system of thousands of tens of thousands of modules is a normal thing, if all together is obviously not good management and there is a possibility of naming conflicts, so

The built-in module is a Python-enabled feature that requires "import" and "use" when using the corresponding functions of the built-in modules.One, Time moduleIn Python, there are usually several ways to represent time: Timestamp (timestamp): Typically, a timestamp represents an offset that is calculated in seconds, starting January 1, 1970 00:00:00.

This article mainly introduces the datetime module in the python time module. The interface of the datetime module is more intuitive and easier to call, if you want to know about the datetime module, you can refer to Python to pro

One, why serialize# The process of converting an original dictionary, list, and other content into a string is called serialization‘‘‘For example, one of the data we calculate in Python code needs to be used for another program, so how do we give it?Now we can think of a method that exists in the file, and then another Python program is read from the file.But we all know that there is no dictionary concept

A previous blog post describes the concepts and basic uses of modules in Python, which act as a basic unit in the Python language and can be used to write common library functions or objects for reuse. At the same time, the module can also be run as a standalone file, previously mentioned, as long as the module file is

methods:Method 1: Ctrl + R (run): pythonMethod 2: Another running method. We can see that double-click script1.py to flash the window. Similar to Ctrl + F5 during VC running, right? What should we do? (Skip this step unless in windows)Here we add a sentence raw_input () to check the effect: Save and double-click script1.py: So what is raw_input?In general, raw_input reads the next row of the standard input and waits until it is obtained. This is equivalent to a cin. Of course, its syntax is qui
