Python supports basic numeric data types such as int, long, and float, just like all major programming languages. None represents a null pointer in Python.
Strings are sequential data types in Python. Other sequential data types that are commonly used in Python are lists and tuples. The difference between a list and tuple is that the former is mutable while the latter is an immutable type. Therefore, the interpreter would throw an error if you try to modify a tuple. Let's dig a little deeper into lists and tuples.
A list is a collection of elements. An element can be of any data type and a list can contain elements of different data types. A list has several important functions such as append, extend, insert, index, pop, and few others. The following table summarizes the functionality of these functions:
Function name | Functionality |
| Adds a new element to the end of the list. |
| Adds new elements from an iterable. The members of the iterable element... |
