Complete Guide To Different Persisting Methods In Pandas

As a Machine learning engineer, it is a common practice to save the data and models in a CSV format. Though CSV format helps in storing data in a rectangular tabular format, it might not always be suitable for persisting all Pandas Dataframes. CSV files tend to be slow to read and write, take up more memory and space and most importantly CSVs don’t store information about data types.

Complete Guide To Different Persisting Methods In Pandas

As a Machine learning engineer, it is a common practice to save the data and models in a CSV format. Though CSV format helps in storing data in a rectangular tabular format, it might not always be suitable for persisting all Pandas Dataframes. CSV files tend to be slow to read and write, take up more memory and space and most importantly CSVs don’t store information about data types.

In this article, we will understand how CSV handles different file formats, explore different ways to store the data and the performance of each of these persisting methods.

9 Useful Pandas Methods You Might Have Not Heard About

They can make your daily work easier and faster.

In this article, I wanted to quickly show a few useful pandas  methods/functions, which can come in handy during your daily work. To manage expectations, this is not an article showing the basic functionalities of pandas  and there is no particular theme to the methods. Without further ado, let’s start!

Practice Problems: How To Use Pandas DataFrames' GroupBy Method

It’s now time for some practice problems! See below for details on how to proceed.

Course Repository & Practice Problems

All of the code for this course’s practice problems can be found in this GitHub repository.

There are two options that you can use to complete the practice problems:

• Open them in your browser with a platform called Binder using this link (recommended)
• Download the repository to your local computer and open them in a Jupyter Notebook using Anaconda (a bit more tedious)

Note that binder can take up to a minute to load the repository, so please be patient.

Within that repository, there is a folder called starter-files and a folder called finished-files. You should open the appropriate practice problems within the starter-files folder and only consult the corresponding file in the finished-files folder if you get stuck.

The repository is public, which means that you can suggest changes using a pull request later in this course if you’d like.

Pandas Vs Numpy: Difference Between Pandas & Numpy [2021]

Python is undoubtedly one of the most popular programming languages in the software development and Data Science communities. The best part about this beginner-friendly language is that along with English-like syntax. It comes with a wide range of libraries. Pandas and NumPy are two of the most popular Python libraries.

Today’s post is all about exploring the differences between Pandas and NumPy to understand their features and aspects that make them unique.
