I recently spent some time exploring CPython, and I want to share some of my adventures here. Allison Kaptur's excellent guide to getting started with Python internals is a bit long-winded, and I'd like to step through my own exploration process to be more organized, This may be followed by other curious Python users.
1. And noticed some strange things.
In the beginning, I just set up nose to test some of the Python 3 code I wrote. When I ran these
Firewalls can be divided into several different security levels. In Linux, because there are many different firewall software options, the security can be low and high, and the most complex software can provide almost no penetration protection capabilities. However, the Linux core itself has a simple mechanism called "Disguise". Apart from the most specialized hacker attacks, it can withstand the vast majority of attacks.When we dial up the Internet,

fly, so ostrich: What is fly? Class bird {public: Virtual void fly (void );...}; Class ostrich: Public bird {...}; For example, from a mathematical point of view, circle is a special ellipse. It is reasonable to say that circle classes can be derived from ellipse classes. However, an elliptic has a long axis and a short axis. If the circle inherits the long and short axes of an elliptic, isn't it superfluous? Therefore, the stricter inheritance rules should be:

10.2 CombinationL "Rule 10-2-1" if logically A is a "part" of B (a), then B is not allowed to derive from a, but rather to be combined with a and other things B.
For example, the Eye (Eye), nasal (Nose), mouth (mouth), ear (EAR) is part of the head, so the class heads should be composed of class Eye, Nose, mouth, Ear combinations, not derived. As shown in the example 10-2-1.

Emperor Qianlong was 88 years old, benefiting from his 42-character health tips: "The teeth are often beaten, the body is often swallowed, the ears are often elastic, the nose is often rubbed, the legs are often run, the surface is often wiped, the foot is often motioned, abdomen always spin, waist often stretch, anus often mention, food do not say, lie not language, drink do not drunk, color do not fan."Qian longhuang's "four tips"

Most write units in python use unittest and mock, and coverage is used to test code coverage. Then, use nose to concatenate all the things so that each time a book is published, all the unit tests of the entire project can be run once. Unittest unittest is not described in detail. Note the following points: the test class inherits unittest. the name of the TestCase test class and test method should start with test. Many tools can run automatically acc

TestI recommend it nose or py.test . I use most of the situation nose . They are basically similar. I'll explain some of the details of nose.Here is an example of the ridiculous use of nose for the creation of a person to test. All functions that begin with the beginning of a test_ file test_ will be called:Def test_equality (): assert True = = FalseAs

This is the hardest part--the nose! This may take a long time, so don't lose heart and try as much as possible.
Use the Rectangular marquee tool and select the nose and the area around it. Select "Filter" from the main menu and go "liquefaction ...". A new window opens, you might want to zoom in a little.
