What does None mean here? - jenniferruurs - Sep-29-2019 What does None mean here? Does it mean that it should be initialized as empty, but if there is input it can be overridden? class ListNode: def __init__(self, data=None, next=None): self.data = data self.next = next RE: What does None mean here? - buran - Sep-29-2019 None is default value of data and next . If you don't pass any of these during instantiation of the class object it will use the default values.as a side note next is built-in function, better don't use it as param name
