Python standard Library at a glance (Python advanced learning)

Write this cause is, or because in the Python challenge, sometimes want to solve problems, even should use which class library do not know, but also to Baidu (I do not believe that I am a person so embarrassed TVT)
It seems that since I learned the basics of Python syntax, I've seen some of the classic Python books and learned about some of the common library types. In the case of several grammar application proficiency, if you do not do the problem, like it can not significantly improve their knowledge reserves (so that you do Python challenge ah, nothing ~ ~).
Therefore, in order to avoid the Python challenge, even want to use the name of the class library is not aware of the embarrassing situation again.
I decided to translate the Python standard library, which is listed here. Do you want to check it soon?

Python Standard Library

Although the Python language reference describes the exact syntax and semantics of the Python language, this library reference book describes the Python standard library. It also describes some of the optional components that are typically included in the Python release.

Python's standard library is very rich, as shown in the following list, which provides a lot of functionality. The library contains built-in modules (written in C) that provide access to the system's functionality, such as file I/O, and a Python module that provides a standardized solution for many problems that occur in daily programming. Some of these modules are explicitly designed to encourage and enhance the portability of the Python program by abstracting out the platform details to the platform-neutral Api.

The Python installer for the Windows platform typically includes the entire standard library, and also contains many additional components. For UNIX operating systems Python is typically provided as a collection of packages, so it may be necessary to use the wrapper tools provided with the operating system to obtain some or all of the optional components.

In addition to the standard library, there are thousands of growing components (from individual programs and module packages to the entire application development framework) that can be downloaded from the Python package index.
