This Pandas exercise project will help Python developers to learn and practice pandas. Pandas is an open-source, BSD-licensed Python library.
Pandas is a handy and useful data-structure tool for analyzing large and complex data. Practice Data analysis using Pandas. For this exercise, we are using Automobile Dataset. This Automobile Dataset has a different characteristic of an auto such as body-style, wheel-base, engine-type, price, mileage, horsepower and many more.
This exercise contains 10 questions. The solution provided for each question. Each question includes a specific Pandas topic you need to learn, When you complete each question you get more familiar with data analysis using pandas. Create two data frames using the following two Dicts, Concatenate those two data frames and create a key for each data frame. Create two data frames using the following two Dicts, Merge two data frames, and append the second data frame as a new column to the first data frame.

Fed up with a ton of tutorials but no easy way to find exercises I decided to create a repo just with exercises to practice pandas. Don't get me wrong, tutorials are great resources, but to learn is to do. So unless you practice you won't learn. Solutions with code and comments. My suggestion is that you learn a topic in a tutorial, video or documentation and then do the first exercises.

We will be using Pandas DataFrame methods merge r and groupby to generate these reports. List of products sold List of products sold Our sales table will have list of products sold.Asia medical supplies pte ltd
List of quantity sold against each products We will use groupby to count total sale against each product. List of quantity and total sales against each product You can un-comment the print commands and check the intermediate results.
We used merge to join two DataFrames and to get Product details price of the product. List of quantity sold against each product and against each store. We will first find out the total price or turnover against each sale by multiplying quantity sold with price of each unit. Once we get the total turnover against each sale, we will use groupby method to find out total sales turnover and quantity against each store. List of customers who have not purchased any product.

Start Now! Pandas is a high-level data manipulation tool developed by Wes McKinney. It is built on the Numpy package and its key data structure is called the DataFrame. DataFrames allow you to store and manipulate tabular data in rows of observations and columns of variables. As you can see with the new brics DataFrame, Pandas has assigned a key for each country as the numerical values 0 through 4.
If you would like to have different index values, say, the two letter country code, you can do that easily as well. Another way to create a DataFrame is by importing a csv file using Pandas. Now, the csv cars. There are several ways to index a Pandas DataFrame. One of the easiest ways to do this is by using square bracket notation. In the example below, you can use square brackets to select one column of the cars DataFrame. You can either use a single bracket or a double bracket.
The single bracket with output a Pandas Series, while a double bracket will output a Pandas DataFrame. You can also use loc and iloc to perform just about any data selection operation.

For those who are not aware of Kaggle. Kaggle is a most popular online community for data scientists and machine learners who can participate in analytical competitions, build predictive models and is a great place for users looking for interesting datasets. We can find all varieties of data including image datasets, CSVs, time-series datasets etc. What is this dataset about? This dataset contains 10 years of data which has total number of forest fires occurred in Amazon rainforest Brazil states for the period to Dataset description:.
Data Cleaning :. Cleaning up data is the first and most important step, as it ensures the quality of the data is met to prepare data for visualisation. Before :. After :. Now we will apply round method to entire dataset using numpy. Boolean Indexing :. Boolean indexing as the name suggests, is used when we want to extract subsets of data from the dataframe based on some conditions.
We can also have multiple conditions which can be grouped in brackets and apply to the dataframe. First, we will perform a vectorised boolean operation that produces a boolean series:. Now, we can use this series to index the whole dataframe, leaving us with the rows that correspond only to employees whose salary is I hope now you have some idea how boolean indexing works.
You can find more info about Boolean Indexing tutorial here. Yes, this is too much to understand for the first time :. So let me break this code and explain it step by step. There you go.!! But, eventually to gain better programming skills we shall work on minimising the coding lines. Visualisation of above dataset:.
