In addition to the keywords (keywords) and the built-in types and functions (builtins), Python provides more functionality through libraries (that is, modules).The Common libraries (modules) are as follows:1) Python Runtime service* The Copy:copy module provides a shallow copy and deep copy of the composite (compound)

Rookie Python Study Notes Day 1: python Study Notes on the use of some function libraries Tuesday, January 3, 2017 It is really difficult for freshman to learn a new computer language. Sometimes I can even check the spelling error of a function for half a day. No way. Who makes my English too bad. I think it is better to learn computer languages from the C langua

easy to use, has a simple programming interface and a simple syntax configuration file. It also supports nested parts of any level, list of values, multiline values, string interpolation, a powerful validation system, including automatic type checking and conversion, repeating parts, default values, saving comments and order keys and chapters, and no external dependencies. ...

Built-in datetime moduleLet's see how other libraries handle this kind of conversion.DateutilWith an instance of the arrow datetime class, you can access Arrow's other useful methods. For example, its humanize() approach translates date times into human-readable phrases like this:Because Maya overlaps with many useful methods in the DateTime library, it can use instances of the Mayadt class, such as using slang_time() methods to convert time offsets t

installation, but its version is not necessarily up to date, so if we want to install the Python third-party library through the PIP tool, we first need to update it to the latest version, simply by typing in the cmd window " pip install --upgrade pip "command.

For example, Python's matplotlib library bar, very convenient and even built-in from the Yahoo finance data on the class, even the regular expression do not have to lose ... C + + is a lot less than the library ... Even if there's a lot of code that looks messy (presumably because of the naming rules, I've seen the C + + code that uses Java naming conventions, which is pretty good, so selectively ignoring me), why is Python's library so humane?

If a strong standard library lays the groundwork for Python 's development, the rich third party libraries is the constant development of python, and with the development of Python some stable third libraries are added to the standard library, where more than 6,000 third-par
