Lists in Python are mutable and when used as a default value of a
parameter for class constructor, its value will be shared between
all class instances.
Example:
class Test:
def __init__(self, mylist=[]):
self.mylist = mylist
A = Test()
B = Test()
A.mylist.append("mylist from instance A")
print(B.mylist) # Will print ['mylist from instance A']
