一、type and members
1. inspect.
getmembers
(
object
[, predicate
]
)
第二个参数通常可以根据需要调用如下16个方法;
返回值为object的所有成员,以(name,value)对组成的列表
inspect.ismodule(object): 是否为模块
inspect.isclass(object):是否为类
inspect.ismethod(object):是否为方法(bound method written in python)
inspect.isfunction(object):是否为函数(python function, including lambda expression)
inspect.isgeneratorfunction(object):是否为python生成器函数
inspect.isgenerator(object):是否为生成器
inspect.istraceback(object): 是否为traceback
inspect.isframe(object):是否为frame
inspect.iscode(object):是否为code
inspect.isbuiltin(object):是否为built-in函数或built-in方法
inspect.isroutine(object):是否为用户自定义或者built-in函数或方法
inspect.isabstract(object):是否为抽象基类
inspect.ismethoddescriptor(object):是否为方法标识符
inspect.isdatadescriptor(object):是否为数字标识符,数字标识符有
__get__
和
__set__属性; 通常也有
__name__和
__doc__属性
inspect.isgetsetdescriptor(object):是否为getset descriptor
inspect.ismemberdescriptor(object):是否为member descriptor
inspect的getmembers()方法可以获取对象(module、class、method等)的如下属性:
TypeAttributeDescriptionNotes
2.
inspect.
getmoduleinf
o
(
path
): 返回一个命名元组<named tuple>(name, suffix, mode, module_type)
name:模块名(不包括其所在的package)
suffix:
mode:open()方法的模式,如:'r', 'a'等
module_type: 整数,代表了模块的类型
3.
inspect.
getmodulename
(
path
):根据path返回模块名(不包括其所在的package)
二、Retrieving source code
1. insp
ect.
getdoc
(
object
): 获取object的documentation信息
2. inspect.
getcomments
(
object
)
3. inspect.
getfile
(
object
): 返回对象的文件名
4.
inspect.
getmodule
(
object
):返回object所属的模块名
5.
inspect.
getsourcefile
(
object
): 返回object的python源文件名;object不能使built-in的module, class, mothod
6.
inspect.
getsourcelines
(
object
):返回object的python源文件代码的内容,行号+代码行
7.
inspect.
getsource
(
object
):以string形式返回object的源代码
8.
inspect.
cleandoc
(
doc
):
三、class and functions
1.
inspect.
getclasstree
(
classes
[, unique
]
)
2.
inspect.
getargspec
(
func
)
3.
inspect.
getargvalues
(
frame
)
4.
inspect.
formatargspec
(
args
[, varargs, varkw, defaults, formatarg, formatvarargs, formatvarkw, formatvalue, join
]
)
5.
inspect.
formatargvalues
(
args
[, varargs, varkw, locals, formatarg, formatvarargs, formatvarkw, formatvalue, join
]
)
6.
inspect.
getmro
(
cls
): 元组形式返回cls类的基类(包括cls类),以method resolution顺序;通常cls类为元素的第一个元素
7. inspect.
getcallargs
(
func
[, *args
]
[, **kwds
]
):将args和kwds参数到绑定到为func的参数名;对bound方法,也绑定第一个参数(通常为self)到相应的实例;返回字典,对应参数名及其值;
>>> from inspect import getcallargs
>>> def f(a, b=1, *pos, **named):
... pass
>>> getcallargs(f, 1, 2, 3)
{'a': 1, 'named': {}, 'b': 2, 'pos': (3,)}
>>> getcallargs(f, a=2, x=4)
{'a': 2, 'named': {'x': 4}, 'b': 1, 'pos': ()}
>>> getcallargs(f)
Traceback (most recent call last):
TypeError: f() takes at least 1 argument (0 given)
四、The interpreter stack
1.
inspect.
getframeinfo
(
frame
[, context
]
)
2.
inspect.
getouterframes
(
frame
[, context
]
)
3.
inspect.
getinnerframes
(
traceback
[, context
]
)
4.
inspect.
currentframe
(
)
5.
inspect.
stack
(
[context
]
)
6.
inspect.
trace
(
[context
]
)
