python, stop variable reassignment in every function call?

Question

Assuming:

def myfunc(x):
    listv  = []
    listv.append(x)

is there a keyword to stop a variable (listv) from being reassigned? Let's suppose that NRA is a keyword:

def myfunc(x):
    NRA listv  = []
    listv.append(x)

...line will be read and not reassigned but the variable still active appending new values for every function call. I know about the GLOBAL variable, but I just want to know is the keyword exists!

Are you asking for what would be a constant deceleration in another language? If so no there is no way to do so in python. — syntaxError, Jun 04 '17 at 05:05
As you see in the answer below, the indentation changes the scope of a variable. — kouty, Jun 04 '17 at 05:49

Variables in functions are not supposed to be persistent between function calls. Because functions are meant to be reusable codes that can be called from different context in the program. So to your answer, NO! There's no keyword for making a variable declared in function persistent.
