Python | Set 3 (Strings, Lists, Tuples, Iterations)
In the previous article, we read about the basics of Python. Now, we continue with some more python concepts.
Strings in Python:
A string is a sequence of characters that can be a combination of letters, numbers, and special characters. It can be declared in python by using single quotes, double quotes, or even triple quotes. These quotes are not a part of a string, they define only starting and ending of the string. Strings are immutable, i.e., they cannot be changed. Each element of the string can be accessed using indexing or slicing operations.

Lists in Python:
Lists are one of the most powerful data structures in python. Lists are sequenced data types. In Python, an empty list is created using list() function. They are just like the arrays declared in other languages. But the most powerful thing is that list need not be always homogeneous. A single list can contain strings, integers, as well as other objects. Lists can also be used for implementing stacks and queues. Lists are mutable, i.e., they can be altered once declared. The elements of list can be accessed using indexing and slicing operations.
The output is:
