Why PyCharm asks me to "Add global statement", when I assigned variable locally?

I wrote this script for illustration purposes only, because I'm getting the same "Context Action" suggestion from PyCharm elsewhere in a larger script (script running fine).

dog = "Hungry"
def animal(status):
    while True:
        if status == "Hungry":
            action = "Feed Me"
        print(action)  # Right here it's highlighting "action" and asking me to add global statement
animal(dog)

Am I not assigning the variable "action" locally within my function "animal()"; and therefore I can freely use it anywhere else within the same function? Can someone explain why it's suggesting to make it a global variable?

Thank you!!!

You are only setting action in the function scope if status == "Hungry", but if status != "Hungry", action is not set in the local scope. Now I can't really tell because you only posted part of you code, but I bet you have a variable named action in the outside scope - PyCharm thinks you want to access that, and therefore wants a global statement. If you do not want to mix the local and outer action, just set it to something else in a else clause:

dog = "Hungry"
def animal(status):
    while True:
        if status == "Hungry":
            action = "Feed Me"
        else:
            action = ""  # just set action to something to make sure it exists either way
        print(action)
animal(dog)
