首先，阅读原文。

其次，使用dir()函数。

Vars (obj)返回对象的属性。

如果您想查看参数和方法，就像其他人指出的那样，可以使用pprint或dir()

如果您想查看内容的实际值，可以这样做

object.__dict__

import pprint

pprint.pprint(obj.__dict__)

or

pprint.pprint(vars(obj))

其他人已经提到了dir()内置，这听起来像是您正在寻找的，但这里有另一个很好的提示。许多库——包括大多数标准库——都是以源代码形式发布的。这意味着您可以很容易地直接阅读源代码。诀窍在于找到它;例如:

>>> import string
>>> string.__file__
'/usr/lib/python2.5/string.pyc'

*。Pyc文件已编译，因此删除后面的'c'，并在您最喜欢的编辑器或文件查看器中打开未编译的*.py文件:

/usr/lib/python2.5/string.py

我发现这对于发现从给定API引发哪些异常等事情非常有用。这种细节在Python世界中很少有良好的文档。

If you want to look inside a live object, then python's inspect module is a good answer. In general, it works for getting the source code of functions that are defined in a source file somewhere on disk. If you want to get the source of live functions and lambdas that were defined in the interpreter, you can use dill.source.getsource from dill. It also can get the code for from bound or unbound class methods and functions defined in curries... however, you might not be able to compile that code without the enclosing object's code.

>>> from dill.source import getsource
>>> 
>>> def add(x,y):
...   return x+y
... 
>>> squared = lambda x:x**2
>>> 
>>> print getsource(add)
def add(x,y):
  return x+y

>>> print getsource(squared)
squared = lambda x:x**2

>>> 
>>> class Foo(object):
...   def bar(self, x):
...     return x*x+x
... 
>>> f = Foo()
>>> 
>>> print getsource(f.bar)
def bar(self, x):
    return x*x+x
