I have a piece of code which looks like below:
a = None
b = None
c = None
d = None
if a==None and b==None and c==None and d==None:
print("All are None")
else:
print("Someone is not None")
What would be the pythonic way or shorter way to achieve this as I have more number of variables to check like this?

You can chain the comparisons:
if a is b is c is d is None:
print("All are None")
else:
print("Someone is not None")

You can use a list, and check all items in the list using list comprehension:
l_list = [None, None, None, None, None]
if all(item is None for item in l_list):
print("All items are None")

if not all((a, b, c, d)):
or
if not any((a, b, c, d)):
if you want to check if any of the item is not None
Does this help?
