How to define variable in class out of class and use it in IF statement-CodePudding

Everyone hello. I have learning Python for 2 months, and now I am learning OOP. And I have a question:

class Test():
x = 0

def __init__(self):

    if Test.x == 5:
        print("OK")
    else:
        print("ERROR")
        
i = Test()
i.x = 5

And this is output:

ERROR

Why this code returns me an "ERROR", if x = 5? In my opinion it may return me an "OK"

CodePudding user response：

When you initialize your Test class x in 0 so you get the ERROR output what you want to do is probably something like this

class Test():
    def __init__(self, value):
        if value == 5:
            print("OK")
        else:
             print("ERROR")

i = Test(5) prints OK
