如何区分调用的是函数还是方法

class MyClass():
    def process(self):
        pass
    
def process():
    pass

print(type(MyClass().process).__name__ == 'method')
print(type(process).__name__ == 'function')

True
True
MyClass.process  False
MyClass.process  True

from types import MethodType, FunctionType
'''
函数： FunctionType
方法： MethodType
'''

print('MyClass.process ', isinstance(MyClass().process, FunctionType))
print('MyClass.process ', isinstance(MyClass().process, MethodType))

print('process ', isinstance(process, FunctionType))
print('process ', isinstance(process, MethodType))

MyClass.process  False
MyClass.process  True
process  True
process  False
