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. 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. Tuples in Python: A tuple is a sequence of immutable Python objects. Tuples are just like lists with the exception that tuples cannot be changed once declared. Tuples are usually faster than lists. Apart from iterating upon a particular condition, we can also iterate on strings, lists, and tuples. Data Structure. Interview Preparation. June 13,

In simple language, a list is a collection of things, enclosed in [ ] and separated by commas. The list is a sequence data type which is used to store the collection of data. Tuples and String are other types of sequence data types. Lists are the simplest containers that are an integral part of the Python language. Lists need not be homogeneous always which makes it the most powerful tool in Python. Lists are mutable, and hence, they can be altered even after their creation. Lists in Python can be created by just placing the sequence inside the square brackets[].

Lists in Python can be created by just placing the sequence inside the square brackets[]. A list may contain duplicate values with their distinct positions and hence, multiple distinct or duplicate values can be passed as a sequence at the time of list creation. In order to access the list items refer to the index number. Use the index operator [ ] to access an item in a list.
