Is there any method named deleteHead() for lists in python? If it exists, what is the use of this method??

Question

Which method should I use to remove first element of list other than pop()

Answer 1

You can use del().

lst = [1,2,3]
del(lst[0])
print(lst) #[2,3]

If you wanted to use this in a deleteHead() function:

def deleteHead(lst):
del(lst[0])

Then you have:

def deleteHead(lst):
del(lst[0])

lst = [1,2,3]
deleteHead(lst)
print(lst) #[2,3]

Another option (if you can't/don't want to use del()) is:

lst = lst[1:]

So

lst = [1,2,3]
lst = lst[1:]
print(lst) #[2,3]

Answer 2

There does not exist a method named a deleteHead() in python 3 . We can use remove () or del method other than pop() to remove an element from the list.
