功能差异

在需要比较的函数中，通过代码获取函数的名称、参数、返回值等信息，再将这些信息进行比较，从而判断出两个函数是否具有相同的功能。

示例代码：

import inspect

def function_one(a, b): return a + b

def function_two(a, b): return a * b

def compare_functions(func1, func2): func1_info = inspect.getfullargspec(func1) func2_info = inspect.getfullargspec(func2)

if func1_info.args == func2_info.args \
    and func1_info.defaults == func2_info.defaults \
    and func1_info.annotations == func2_info.annotations \
    and func1_info.return_annotation == func2_info.return_annotation:
    print("Functions have same signature")
else:
    print("Functions have different signatures")

if func1(2, 3) == func2(2, 3):
    print("Functions have same output for inputs (2, 3)")
else:
    print("Functions have different output for inputs (2, 3)")

compare_functions(function_one, function_two) # Output: Functions have different signatures, Functions have different output for inputs (2, 3)
