Pandas is a python tool used extensively for data analysis and manipulation. Recently I’ve been using pandas with large DataFrames (>50M rows) and through the PyDataUK May Talks and exploring StackOverflow threads have discovered several tips that have been incredibly useful in optimising my analysis.
This tutorial is part 1 of a series and aims to give an introduction to pandas and some of the useful features it offers while exploring the Palmer Penguin dataset.
In this article, we will go through:

In this part, we will explore more about pandas library and its uses in data science.
I will continue from where I left. If you haven’t seen part 2. Please visit https://medium.com/analytics-vidhya/getting-started-with-data-science-with-python-part-2-e3cc3411ac70. Because it will help you to understand.
Now we will mainly focus on commands.
df.describe(): This commads tells us some important stuff about integer columns. Lets do it and see.

Pandas is one of the predominant data analysis tools which is highly appreciated among data scientists. It provides numerous flexible and versatile functions to perform efficient data analysis.
In this article, we will go over 3 pandas tricks that I think will make you a more happy pandas user. It is better to explain these tricks with some examples. Thus, we start by creating a data frame to wok on.
The data frame contains daily sales quantities of 3 different stores. We first create a period of 10 days using the
date_range function of pandas.
import numpy as np import pandas as pd days = pd.date_range("2020-01-01", periods=10, freq="D")
The days variable will be used as a column. We also need a sales quantity column which can be generated by the
randint function of numpy. Then, we create a data frame with 3 columns for each store.

The opportunities big data offers also come with very real challenges that many organizations are facing today. Often, it’s finding the most cost-effective, scalable way to store and process boundless volumes of data in multiple formats that come from a growing number of sources. Then organizations need the analytical capabilities and flexibility to turn this data into insights that can meet their specific business objectives.
This Refcard dives into how a data lake helps tackle these challenges at both ends — from its enhanced architecture that’s designed for efficient data ingestion, storage, and management to its advanced analytics functionality and performance flexibility. You’ll also explore key benefits and common use cases.
As technology continues to evolve with new data sources, such as IoT sensors and social media churning out large volumes of data, there has never been a better time to discuss the possibilities and challenges of managing such data for varying analytical insights. In this Refcard, we dig deep into how data lakes solve the problem of storing and processing enormous amounts of data. While doing so, we also explore the benefits of data lakes, their use cases, and how they differ from data warehouses (DWHs).
This is a preview of the Getting Started With Data Lakes Refcard. To read the entire Refcard, please download the PDF from the link above.

If you accumulate data on which you base your decision-making as an organization, you should probably think about your data architecture and possible best practices.
If you accumulate data on which you base your decision-making as an organization, you most probably need to think about your data architecture and consider possible best practices. Gaining a competitive edge, remaining customer-centric to the greatest extent possible, and streamlining processes to get on-the-button outcomes can all be traced back to an organization’s capacity to build a future-ready data architecture.
In what follows, we offer a short overview of the overarching capabilities of data architecture. These include user-centricity, elasticity, robustness, and the capacity to ensure the seamless flow of data at all times. Added to these are automation enablement, plus security and data governance considerations. These points from our checklist for what we perceive to be an anticipatory analytics ecosystem.
