Python Learning: Variable __python

Python is the first language I've learned that does not require modifiers to modify a variable, declare a variable by simply writing a variable name and assigning a value to it, for example:

#变量名只能是由字母, numbers and underscores, and cannot begin with a number
#Python只需要这样就可以声明一个变量了, so Python has no strictly constant
name = "Zoneday"
#如果要声明一个常量, You can capitalize all the variable names, which is a conventional way to tell others that this is a constant and not to be modified. (Although must modify also can modify ~ ~)
NAME = "Zoneday"
