David Yeoman Having looked at the Python date and datetime modules in previous articles, today we’ll take a closer look at the time module and understand how to extract, input, and work with times in our coding. First, I’ll recap on computer time and introduce the time object we’ll be using with the functions we introduce later … Read more
Article Overview: In a previous post, we discussed the datetime module in Python and used it to iterate through a range of dates. Today, let’s learn how to manage timezones in Python using the datetime module and a third-party package called dateutil. I aim to choose a range of world cities and print the local … Read more
A question frequently asked in programming forums concerns the use and iteration of dates in Python. Today I wish to introduce the basics of the datetime module in Python, which will allow us to output a range of dates, given a date input and the number of days needed. We will also look at creating … Read more
A common problem people often run up against in Python is understanding a method to sort one list based on the values in another.

In this article, we will cover what config files are before introducing the Python … Read more
There comes a time in all our coding lives when we need to compare lists to understand whether items in one list appear in a second list. In this article we’ll start where we all started, using for-loops, before moving to a more classic Python list comprehension. We’ll then move beyond that to use Python … Read more
A Quick Introduction To Python’s ‘re’ Module “How to extract digits or numbers from a string” is a common search by Python users in Google, and a frequent query in forums such as Stack Overflow.
