in this article, I am going to explain in detail the Pandas Dataframe objects in python. In the previous article in this series Learn Pandas in Python, I have explained what pandas are and how can we install the same in our development machines. I have also explained the use of pandas along with other important libraries for the purpose of analyzing data with more ease. Pandas provides a dataframe
In this article, I am going to explain how to use Pandas in Python. Pandas is one of the most popular modules in python that can be used for data manipulation and analysis using python. Basically, it provides an easy interface to interact with flowing data and apply transformations to them on the go. This module is covered under the BSD license and can be used for free. You can download this module by visiting the website or by installing it through the python package manager.
Pandas provide us with a range of data analysis options such as reading data from files and databases, to applying various transformations within the data frames, slicing and dicing the data, and then writing the data back to a database or prepare it for a visualization tool to be fed to. Pandas can also visualize data within the python environment by importing another module known as matplotlib and display stunning visuals within it. However, for the scope of this article, we will stick to learning Pandas in python only. As per the definition provided by Wikipedia, “_The name Pandas is derived from the term ‘panel data’, an econometrics term for data sets that include observations over multiple time periods for the same individuals_”. Over the last few years, this module has been gaining popularity and this can be explained if we see the search trends from Stack Overflow.

If you see the above graph, it is clearly visible that in recent years, the trend of using Pandas has increased exponentially and it is now one of the most common modules used by the entire data science community.
In this post, we will learn about pandas’ data structures/objects. Pandas provide two type of data structures:- ### Pandas Series Pandas Series is a one dimensional indexed data, which can hold datatypes like integer, string, boolean, float...
Pandas is a fast, powerful, flexible and easy to use open source data analysis and manipulation tool, built on top of the Python programming language.

Python Pandas dataframe append() is an inbuilt function that is used to add rows in the dataframe. The loc and iloc is also way to add or modify rows.
Pandas is built on the NumPy package and its key data structure is called the Dataframe. There’s also another data structure supported by Pandas, called Series. We’ll be learning more about both the Series and Dataframes in this article.Pandas is mainly used for data manipulation, visualization of the data, building machine learning tools, etc. If we are using Pandas in Python, we have to be familiar with the NumPy library.
