Class variables
#1
Given the scenario
class SomeClass: myvar = 0 def __init__(self): do stuff here def func(self): do stuff here myvar += 1 print(myvar)
Would not myvar be a global for the class?
I'm getting that it has not been assigned in the function.
Input much appreciated
I welcome all feedback.
The only dumb question, is one that doesn't get asked.

I'd say that you haven't received a reply because your question obfuscates your problem. You don't have an example of usage or any error code. That aside I have a bit of advise on your problem.

Class variables are accessed the same way that instance variables are accessed, that is by way of an instance.

class SomeClass: myvar = 0 def __init__(self): do stuff here def func(self): do stuff here myvar += 1 print(myvar) my_instance = SomeClass() print(my_instance.myvar) #Unlike some other languages class variables in python are not accessed by the class name

Here is an example of accessing the class variable and the instance variable
class SomeClass: myvar = 0 def __init__(self): self.myvar = 10 def increase_class_variable(self): SomeClass.myvar += 1 print(f'Shared class variable: {SomeClass.myvar}') def increase_instance_variable(self): self.myvar += 1 print(f'Instance variable: {self.myvar}') instance1 = SomeClass() instance2 = SomeClass() instance1.increase_class_variable() instance1.increase_class_variable() instance2.increase_class_variable() instance1.increase_instance_variable() instance1.increase_instance_variable() instance2.increase_instance_variable()
Output:
Shared class variable: 1 Shared class variable: 2 Shared class variable: 3 Instance variable: 11 Instance variable: 12 Instance variable: 11
