Overview of this book

Have you always wanted to learn Python, but never quite known how to start? More applications than we realize are being developed using Python because it is easy to learn, read, and write. You can now start learning the language quickly and effectively with the help of this interactive tutorial. The Python Workshop starts by showing you how to correctly apply Python syntax to write simple programs, and how to use appropriate Python structures to store and retrieve data. You'll see how to handle files, deal with errors, and use classes and methods to write concise, reusable, and efficient code. As you advance, you'll understand how to use the standard library, debug code to troubleshoot problems, and write unit tests to validate application behavior. You'll gain insights into using the pandas and NumPy libraries for analyzing data, and the graphical libraries of Matplotlib and Seaborn to create impactful data visualizations. By focusing on entry-level data science, you'll build your practical Python skills in a way that mirrors real-world development. Finally, you'll discover the key steps in building and using simple machine learning algorithms. By the end of this Python book, you'll have the knowledge, skills and confidence to creatively tackle your own ambitious projects with Python.

2. Python Structures

Activity 6: Using a Nested List to Store Employee Data

Solution:

  1. Begin by creating a list, adding data, and assigning it to employees:
    employees = [['John Mckee', 38, 'Sales'], ['Lisa Crawford', 29, 'Marketing'], ['Sujan Patel', 33, 'HR']]
    print(employees)

    You should get the following output:

    Figure 2.31: Output when we print the content of employees

  2. Next, we can utilize the for..in loop to print each of the record's data within employee:
    for employee in employees:
        print(employee)

    Figure 2.32: Output when printing each of the records inside employees

  3. To have the data presented in a structured version of the employee record, add the following lines of code:
    for employee in employees:
        print("Name:", employee[0])
        print("Age:", employee[1])
        print("Department:", employee...
