About List:

• To create an empty list we need to use []
  • Example: data = []
• Items in the List are separated with the comma (,)
• List is Mutable(i.e. Mutable is when something is changeable)
• We can store different types of data in a List that is called Heterogeneous.
• List is a ordered
• You can access the list elements by index

Remove an element from a list in Python:

You can use clear(), pop(), remove() and del() methods to remove elements from a list.

methods are:

• clear()
• pop()
• remove()
• del()

Using clear() method: in python, you can remove all elements using the clear() method.

new_list = [10, 20, 30]
new_list.clear()
print(new_list)
OUTPUT:[]

Using POP() method: You can remove the element at the specified index and get its value with pop().

Note:

• index starts with 0 (ZERO)
• pop() method removes and returns the last item if the index is not provided.

new_list = [10, 20, 30, 40, 50, 60, 100]
print(new_list.pop(0))
OUTPUT:10

Using Remove() method:

By using remove() method you can remove the first matching element from a list.

new_list = [2, 9, 3, 5, 7, 9, 11]
new_list.remove(9)
print(new_list)
OUTPUT:[2, 3, 5, 7, 9, 11]

By using del() method:

You can delete the element using the del() method by specifying the index of the item.

new_list = [0, 10, 20, 30, 40, 50]
del new_list[0]
print(new_list)
OUTPUT:[10, 20, 30, 40, 50]

You can delete multiple values from a list using slice:

new_list = [5, 10, 20, 30, 40, 50, 60, 70]
del new_list[2:5]
print(new_list)
OUTPUT:[5, 10, 50, 60, 70]
