Changing static class variables

Question

How is it possible to change static variables of a class? I want it to be changed by some sort of input.

class MyClass: 
    
    var1 = 1
    var2 = 4

    def __init__(self, var3, var4):
        self.var3 = var3
        self.var4 = var4

It is var1 og var2 that i want to be changable, or want to know how to change.

Answer 1

class Whatever():
    b = 5
    def __init__(self):
        Whatever.b = 9999

boo = Whatever()
print(boo.b) # prints 9999

boo.b = 500
print(boo.b) # prints 500

Whatever.b = 400
print(boo.b) # prints 500

# since its a static var you can always access it through class name
# Whatever.b
