如果你有兴趣查看对象myobj对应的函数的源代码，你可以输入iPython或Jupyter Notebook:

myobj ? ?

Python有一组强大的自省特性。

看看下面的内置函数:

(型) dir () (id) getattr () hasattr () globals () locals () callable ()

Type()和dir()分别对于检查对象的类型及其属性集特别有用。

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__

Vars (obj)返回对象的属性。

检查代码的两个好工具是:

IPython。一个允许你使用制表符完成检查的python终端。 使用PyDev插件的Eclipse。它有一个优秀的调试器，允许您在给定的位置中断，并通过浏览所有变量作为树来检查对象。您甚至可以使用嵌入式终端在该位置尝试编码或键入对象并按'。，让它为你提供代码提示。

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
