局部变量(local variable):在函数中定义的参数和变量是局部变量,在函数外是无法使用的,因为函数调用完之后,栈就将函数数据清除,所以外部是无法调用的 全局变量(global variable):作用域是整个模块,整个代码都可以访问,可以在函数中使用,最好不要在函数中修改,如果在函数中修改全局变量,会在函数中,新建一个局部变量,...
#AttributeError: Person instance has no attribute 'name' #那是因为,虽然当前的实例self中,没有在__init__中初始化对应的name变量,实例self中没有对应的name变量 #但是由于实例所对应的类Person,有对应的name变量,所以也是可以正常执行代码的 #对应的,此处的,实际上是 print 'My name is %s'%(); # -> ...

If you try to understand the above specified declaration, you will find that in python the keyword ‘def’ is used to begin the declaration of a function. This is followed by the function name and comma separated arguments in the parenthesis. ...
The*argsand**kwargsis an approach to pass multiple arguments to aPython function. They allow to pass a variable number of arguments to a function. However, please note it is not necessary to name the variables as*argsor**kwargsonly. Only the*is important. We could also name the variable...

TypeError: demo() missing 2 required positional arguments: 'name' and 'age' Variable Function Arguments in Python Till now we have seen the fixed function arguments in Python. We have also learned that when we try to pass the variable arguments while calling a function, we get an error. No...
