Python for Machine Learning

Sir i am benerplz help me

If you append a list of elements into a new list then it will be appended as single value for example
l = [1,2,3] is your list you want to append a new list l1 = [4,5,6] then it gives list l as [1,2,3,[4,5,6]] the length of the list will be 4. Whereas by using extend l = [1,2,3] and l1 = [4,5,6] extend gives l = [1,2,3,4,5,6] hence length is 6.This is the difference between methods append and extend. I hope this is helpful.

Tuple has this bracket () while list has this []
