Linear Probing in Python About to get back into coding, so I implemented linear probing in Python. How did I do? Anything unnecessary? Am I using "global" right? I originally wanted to use an array with a fixed length, but couldn't get it to work.

list = ["x", "x", "x", "x", "x", "x", "x"]
state = 0

def main():
#tests
    linearProbing(1)
    linearProbing(1)
    linearProbing(1)
    print(list)

def linearProbing(x):
    global state
    global list
    c = x % len(list)
    while state != 1:
        if list[c] == "x":
            list[c] = x
            state = 1
        elif c == 0:
            c = len(list) - 1
        else:
            c -= 1
    state = 0

if __name__ == '__main__':
    main()
Am I using "global" right?


It would be better to not use global at all,
by wrapping this in a class,
with state and list as attributes,
so an instance could reference them with self.state, for example.


  How did I do?


state is used as a boolean.
So it should be a boolean value,
set to False instead of 0 and True instead of 1 values.

list is not a good name for a variable,
as it shadows a built-in with the same name.

A quick tip: you can write ["x", "x", "x", "x", "x", "x", "x"] simpler as ["x"] * 7.
In any case, duplicating "x" in multiple places (first when you initialize list, and then later in linearProbing), is not great.
It would be better to put the value "x" in a variable, say FREESPOT = "x",
and reuse that everywhere.
