lint for Python？ [英] lint for Python?
问题描述
我一直在为Python搜索一个好的多模块lint检查器和
我还没找到一个。
Pylint只在一个单独的模块中检查错误是一项不错的工作。
这是我的一个问题。我有两个模块。
在模块一中，我有一个功能：
def foo（主机，用户ID，密码）：
通过
在模块二中，我称之为函数：
foo（用户名，密码）
lint没有发现错误，在程序运行时它被称为
之前不会被捕获。我不希望凌晨3点发现错误。
我从未使用过那种没有发现错误的语言。我很惊讶Python正被许多主要的b
公司使用。你是如何发现这些类型的错误的？
我已经和Wing的技术支持人员谈过了，他们并没有意识到
多模块lint但他们正在考虑将自己的lint放入他们的IDE中。
谢谢
I''ve been searching for a good multi-module lint checker for Python and
I haven''t found one yet.
Pylint does a decent job at checking for errors only within a single module.
Here''s one of my problems. I have two modules.
In module one, I have a function:
def foo( host, userid, password ):
pass
In module two, I call that function:
foo( userid, password)
lint doesn''t find that error and it won''t be caught until it''s called
while the program is running. I don''t want that error found at 3AM.
I''ve never used a language that didn''t catch that type of error. I''m
quite surprised that Python is being used by a number of major
companies. How you catch these types of errors?
I''ve spoken to tech support at Wing and they weren''t aware of a
multi-module lint but they''re considering putting their own lint into
their IDE.
Thank you

Pylint在检查方面做得不错仅在单个模块中出现错误。

lint没有发现错误，直到它被调用时才会被抓住，而程序正在运行。

简而言之（或短语）：单元测试。大量的单元测试，
可以捕获这样的愚蠢错误和更复杂的逻辑
错误。
查看''unittest''模块
[ http：//docs.python .org / library / unittest.html] 以及关于该主题的许多
着作中的任何一篇，以获取更多信息。我肯定其他一些
海报会回复更全面的解释。
干杯，

In a word (or phrase rather): unit testing. Lots of unit testing,
which catches both silly errors like this and more complicated logic
errors.
Check out the ''unittest'' module
[http://docs.python.org/library/unittest.html] and any of the many
writings on the subject for more information. And I''m sure some other
posters will respond with more thorough explanations.
Cheers,
Chris

因为在Python中，它不一定是错误的。您在
中定义的每个名称Python只是一个变量，并且可以随时更改其值：
编译器无法告诉foo不会在函数的定义和实际调用之间有一个不同的值
。
Because in Python, it''s not necessarily an error. Every name you define in
Python is just a variable, and can have its value changed at any time: the
compiler can''t tell that foo won''t have a different value put into it
between the definition of the function and the actual call.

然后不要进行深夜（或早上
早上）的单元测试。 ;-)
除了标准库中的`unittest`模块，你可能会看到`$。$`和`鼻子`的
。

Then don''t run the unit tests that late at night (or early in the
morning). ;-)
Besides the `unittest` module from the standard library you might look
into `py.test` and `nose`.
