Don't know how list are implemented in Python. But in the dumb linked list implementation (like C++ std::list), each element has a "next" member that point the the next element. So, to have list length, you have to do (pseudo code, not actual python code):
len = 0
elt = list.fisrt
while exist(elt):
elt = elt.next
len++
return len
Whereas to test if list is empty, you just have to:
return exist(list.first)
I comment because this is how a social network works, and this is how you keep lemmy alive. My comment has generated a dozen of other comments, so he achieved his goal.
There is not a single question that's already have been answered on internet, so there no point on asking anything on social plateforms except just for the sake of interacting with other peoples.
Lemmy is not stackoverflow ๐
