inspect模块是针对模块,类,方法,功能等对象提供些有用的方法。例如可以帮助我们检查类的内容,检查方法的代码,提取和格式化方法的参数等。
import inspect
import os class Test(object):
"""Test Class """ def test(self):
self.fuc = lambda x: x class Testone(Test):
pass print(inspect.ismodule(os)) # True
print(inspect.isclass(Test)) # True
print(inspect.getdoc(Test)) # Test Class print(inspect.getsourcefile(Test)) # 文件路径
print(inspect.getsourcelines(Test)) # 代码块,每行一个元素,组成数组
print(inspect.getsource(Test)) # 获取代码块原本内容,带缩进
打印全局中的变量
#打印全局变量中的模块对象
myglobals = {}
myglobals.update(globals())
modules = [value
for key, value in myglobals.items()
if inspect.ismodule(value)]
print(modules) 输出结果:
[<module 'builtins' (built-in)>, <module 'inspect' from 'D:\\python\\python\\lib\\inspect.py'>, <module 'os' from 'D:\\python\\python\\lib\\os.py'>]
查看类和类对象有哪些方法可以调用
# 查看类的可调用方法
for name, value in inspect.getmembers(Test, callable):
print(" Callable:", name) for name, value in inspect.getmembers(Test(), callable):
print(" Instance Callable:", name)
获取栈的全部调用信息
def debug():
import inspect
print(inspect.stack()[0][3])
print(inspect.stack()[1][3])
caller_name = inspect.stack()[1][3]
# print("[DEBUG]: enter {}()".format(caller_name) ) def say_hello():
debug()
# print("hello!") def say_goodbye():
debug()
# print("goodbye!") if __name__ == '__main__':
say_hello()
say_goodbye() 运行结果:
debug
say_hello
debug
say_goodbye
