How to declare list in python?

A list is a data structure, or it can be considered a container that can be used to store multiple data at once. The list will be ordered and there will be a definite count of it. The elements are indexed according to a sequence and indexing is done with 0 as the first index.

To create a list you separate the elements with a comma and enclose them with a bracket”[]”.

e.g.,

a=["Python", "C++", "C", "Java"]
print(a)

We can create a two dimensional list. This is done by nesting a list inside another list.

e.g.,

a=[['1', '2'], ['3', '4']]
print(a)

Some basic function to modify list are:-

• list.append() – This function will add another element to the list at the end.

syntax:-

lst=[]
lst.append("name_of_element")

• list.insert() – This will add another element to the list at the given index, shifting the elements greater than the index one step to the right.

syntax:-

lst=[]
lst.insert(index_number, "Element_name")

• list.pop() – This function will remove the last element from the list. If the index is provided, then it will remove the element at the particular index.

syntax:-

lst=[]
lst.pop(index_number)

This is all about lists in python.
