Hello,
Weird issue I've found on Windows images in Azure Devops Pipelines and
Github actions. Printing Unicode characters fails on these images because,
for some reason, the encoding is mapped to cp1252. What is particularly
weird about the code page being set to 1252 is that if you execute "chcp"

You can define a classmethod in SubClass that seems to do the job:
class SuperClass(object):
@staticmethod
def spam(): # "spam" and "eggs" are a Python tradition
print('spam from SuperClass')
class SubClass(SuperClass):

def eggs(self):
super().
yes,
just use SubClass.foo
at least this works for me:
class SuperClass:
@staticmethod
def test():
print("yay")
class SubClass(SuperClass):
def __init__(self):
super().__init__()
SubClass.test()
subclass = SubClass()
Output:

yay
