3 Python Pandas Tricks for Efficient Data Analysis

Explained with examples.

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.

Your Data Architecture: Simple Best Practices for Your Data Strategy

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.

PANDAS: Most Used Functions in Data Science

Most useful functions for data preprocessing

When you get introduced to machine learning, the first step is to learn Python and the basic step of learning Python is to learn pandas library. We can install pandas library by pip install pandas. After installing we have to import pandas each time of the running session. The data used for example is from the UCI repository “https://archive.ics.uci.edu/ml/datasets/Heart+failure+clinical+records

An introduction to exploratory data analysis in python

Many a time, I have seen beginners in data science skip exploratory data analysis (EDA) and jump straight into building a hypothesis function or model. In my opinion, this should not be the case. We should first perform an EDA as it will connect us with the dataset at an emotional level and yes, of course, will help in building good hypothesis function.

EDA is a very crucial step. It gives us a glimpse of what our data set is all about, its uniqueness, its anomalies and finally it summarizes the main characteristics of the dataset for us. In this post, I will share a very basic guide for performing EDA.

**Step 1: Import your data set **and have a good look at the data.

In order to perform EDA, we will require the following python packages.

Packages to import:

import numpy as np
	import pandas as pd
	import matplotlib.pyplot as plt
	import seaborn as sns
	from collections import defaultdict
	%matplotlib inline
view raw
exploratory_analysis1.py hosted with ❤ by GitHub

Once we have imported the packages successfully, we will move on to importing our dataset. You must be aware of read_csv() tool from pandas for reading csv files.

Import the dataset:

For the purpose of this tutorial, I have used Loan Prediction dataset from Analytics Vidhya. If you wish to code along, here is the link.

The dataset has been successfully imported. Let’s have a look at the Train dataset.
