如果你对此感兴趣，可以看看objbrowser。它使用Python标准库中的inspect模块进行下面的对象内省。

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__

你可以在shell中使用dir()列出对象的属性:

>>> dir(object())
['__class__', '__delattr__', '__doc__', '__format__', '__getattribute__', '__hash__', '__init__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__']

当然，还有inspect模块:http://docs.python.org/library/inspect.html#module-inspect

如果您正在寻找一个稍微更微妙的解决方案，您可以尝试objprint。它的一个积极的方面是它可以处理嵌套对象。例如:

from objprint import objprint

class Position:
    def __init__(self, x, y):
        self.x = x
        self.y = y

class Player:
    def __init__(self):
        self.name = "Alice"
        self.age = 18
        self.items = ["axe", "armor"]
        self.coins = {"gold": 1, "silver": 33, "bronze": 57}
        self.position = Position(3, 5)

objprint(Player())

会打印出来

<Player
  .name = 'Alice',
  .age = 18,
  .items = ['axe', 'armor'],
  .coins = {'gold': 1, 'silver': 33, 'bronze': 57},
  .position = <Position
    .x = 3,
    .y = 5
  >
>

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

>>> 

在Python 3.8中，你可以使用__dict__. __dict__来打印对象的内容。例如,

class Person():
   pass

person = Person()

## set attributes
person.first = 'Oyinda'
person.last = 'David'

## to see the content of the object
print(person.__dict__)  

{"first": "Oyinda", "last": "David"}
