Functions in Python are first-class citizens. It means that functions have equal status with other objects in Python. Functions can be assigned to variables, stored in collections, or passed as arguments. This brings additional flexibility to the language. Python function types There are two basic...
In Python, data types are used to specify the type of data that a variable can hold. Python has a dynamic type system, which means that variables can change their data type during the program’s execution. We have several basic data types that are used most frequently. These data types i...

# 摘自 types.py def_f:pass FunctionType = type(_f) class_C: def_m(self):pass MethodType = type(_C._m) 这里只是定义了两个空的 _f 和 _m,然后就使用了内置的 type 函数。所以,我们完全可以把它们摘出来,看看庐山真面目: 梳理它们的关系,可以得到: ...
我们还看到了types.FunctionType及types.MethodType,它们指的就是目标类。继续点进去看源码: 代码语言:javascript 复制 # 摘自 types.py def_f():pass FunctionType=type(_f)class_C:def_m(self):pass MethodType=type(_C()._m) 这里只是定义了两个空的 _f() 和 _m(),然后就使用了内置的 type() 函数...
