Python  inspect 模块的简单使用及常用方法

import inspect
def who_am_i():
    # 输出当前文件绝对路径
    print(inspect.currentframe().f_code.co_filename)
    return inspect.currentframe().f_code.co_name
print(who_am_i())  # 输出: who_am_i

import inspect
def caller_info():
    frame = inspect.currentframe().f_back
    print(f调用者 {frame.f_code.co_filename} 调用行号 d{frame.f_lineno}")
def test():
    caller_info()  # 调用以获取调用者信息
test()

import inspect
def sample_function(name, age=25):
    pass
sig = inspect.signature(sample_function)
print(sig)  # 输出: (name, age=25)

import inspect
def my_function():
    """A simple function."""
    pass
print(inspect.getsource(my_function))

class MyClass:
    def method_one(self):
        pass
    def method_two(self):
        pass
# 获取类的所有成员方法
methods = inspect.getmembers(MyClass, predicate=inspect.isfunction)
print(methods)  # 输出 MyClass 中定义的方法

def test():
    # 获取调用方
    frame = inspect.currentframe().f_back
    # 获取调用方文件绝对路径
    caller_file = inspect.getfile(frame)
    # 这种方式也可以
    caller_file = frame.f_code.co_filename
    ...
    params = [
        caller_file,
        "--env-data",
        env_data.json(),
        f"--count={count}",
        "-m",
        mark,
    ]
