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, Python, Python, Python-list.

Advanced Python List Methods and Techniques.

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.

Have the answer already? Yes, you'd probably write down a shopping list! This post is a beginner-friendly tutorial on Python lists. Over the next few minutes, we'll get to know lists and cover some of the most common operations such as slicing through lists and modifying them using list methods. For Python to recognize our list, we have to enclose all list items within square brackets [ ] , with the items separated by commas. Just the way that we can always modify our shopping list by reordering items — do things like replacing oatmeal cookies with our favorite candy , for example — we can do the same with Python lists. For this reason, lists are mutable. Did you notice that oatmeal cookies is the third item in the list, but is at index 2? Well, this is because of zero-indexing. In Python, index is essentially an offset from the beginning of the list.

Learn Python practically and Get Certified. Python lists store multiple data together in a single variable. Suppose, we need to store the age of 5 students, instead of creating 5 separate variables, we can simply create a list:. We create a list by placing elements inside square brackets [] , separated by commas. For example,. Each element in a list is associated with a number, known as a list index.
