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']
