python信息功能:它在哪里?


Dive into Python开始:

Python has a function called info. Try it yourself and skim through
the list now.

>>> from apihelper import info
>>> import __builtin__
>>> info(__builtin__, 20)
ArithmeticError      Base class for arithmetic errors.
AssertionError       Assertion failed.
AttributeError       Attribute not found.
EOFError             Read beyond end of file.
EnvironmentError     Base class for I/O related errors.
Exception            Common base class for all exceptions.
FloatingPointError   Floating point operation failed.
IOError              I/O operation failed.

事实证明,Python没有名为info的函数.这本书指的是什么?

最佳答案 我不知道为什么Dive Into Python声称“Python有一个叫做info的函数”,但显然不是这样.

apihelper.py(从中导入信息)在本书in section 4.1的前面描述,它只是Mark Pilgrim编写的用于Dive Into Python的模块.该apihelper模块显然确实包含一个信息函数,该函数执行您链接的4.3.3节中声明的内容.
