Overview of this book

The Pandas Workshop will teach you how to be more productive with data and generate real business insights to inform your decision-making. You will be guided through real-world data science problems and shown how to apply key techniques in the context of realistic examples and exercises. Engaging activities will then challenge you to apply your new skills in a way that prepares you for real data science projects. You’ll see how experienced data scientists tackle a wide range of problems using data analysis with pandas. Unlike other Python books, which focus on theory and spend too long on dry, technical explanations, this workshop is designed to quickly get you to write clean code and build your understanding through hands-on practice. As you work through this Python pandas book, you’ll tackle various real-world scenarios, such as using an air quality dataset to understand the pattern of nitrogen dioxide emissions in a city, as well as analyzing transportation data to improve bus transportation services. By the end of this data analytics book, you’ll have the knowledge, skills, and confidence you need to solve your own challenging data science problems with pandas.

Solution 4.1

Perform the following steps to complete the activity:

  1. Open a new Jupyter notebook and select the Pandas_Workshop kernel.
  2. Import the pandas package:
    import pandas as pd
  3. Load the CSV file as a DataFrame:
    file_url = 'https://raw.githubusercontent.com/PacktWorkshops/The-Pandas-Workshop/master/Chapter04/Data/car.csv'
    data_frame = pd.read_csv(file_url)
  4. Display the first 10 rows of the DataFrame:
    data_frame.head(10)

The output will be as follows:

Figure 15.10 – Displaying the top 10 rows of the DataFrame

You can see some missing data (NaN) in a couple of columns. Displaying the DataFrame details with the info() function should help us to confirm this.

  1. Display the data types of each column in the DataFrame using the info() method:
    data_frame.info()

The output will be as follows:

As suspected, most columns have...
