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.

3. Executing Python – Programs, Algorithms, Functions

Activity 8: What's the Time?

Solution:

In the following, you will find the solution code to Activity 8, What's the Time?

To make it easier to understand, the code has been broken down with explanations:

current_time.py:

"""
This script returns the current system time.
"""
  1. Firstly, we import the datetime library, which contains a range of useful utilities for working with dates:
    import datetime
  2. Using the datetime library, we can get the current datetime stamp, and then call the time() function in order to retrieve the time:
    time = datetime.datetime.now().time()
  3. If the script is being executed, this if statement will be true, and, therefore, the time will be printed:
    if __name__ == '__main__':
        print(time) 

    You should get the following output:
