I was working on a financial reporting project for a client in the USA, and I ran into a common formatting issue. The numbers in my report appeared to be 45.6000 or 120.000. At first glance, this might not seem like a big deal. But when you’re preparing reports for stakeholders, clean and precise formatting … Read more >>
When I started working with financial data in Python, I often needed to remove decimal numbers from values. For example, when processing sales reports from different states in the USA, I had to clean up amounts like 1234.56 into 1234. At first, I thought there was just one way to do it. But with more … Read more >>
Recently, I was working on a project where I had to manage counters in a simulation model. Coming from a C++ background, I instinctively typed i++, only to realize Python doesn’t support it. This got me thinking: many beginners who switch to Python from other languages face the same confusion. In Python, there are no … Read more >>
While reviewing a client’s automation script, I ran into an error that read: At first glance, it looked confusing because the code seemed fine. However, after digging deeper, I realized the issue was caused by hidden or invalid characters in the script. If you’ve been coding in Python long enough, you’ll likely face this error … Read more >>
While working on a data processing script, I needed to loop through a list of customer records. The issue was, I wasn’t sure if the object I received from an API was even iterable. If you’ve been coding in Python for a while, you’ve probably run into the same problem. Sometimes, you expect a list … Read more >>
Recently, I was working on a project where I had to organize student test scores stored in a list of lists. Each sublist contained the student’s name and score. At first, I thought sorting this kind of nested list would be tricky. But after experimenting with Python’s built-in functions, I realized there are several simple … Read more >>
When I was working on a text formatting project, I needed to make strings look “stylized” by capitalizing every alternate letter. At first, I thought Python might have a built-in function for this. But soon, I realized I needed to use a combination of string methods, slicing, and loops to achieve it. In this tutorial, … Read more >>
Recently, I was working on a project where I needed to extract the first and last digit of a number in Python. At first, I thought Python might have a built-in function for this. But just like in Excel, where some features require workarounds, in Python, we need to use a few tricks. In this … Read more >>
I was working on a project where I needed to extract the first digit of a number in Python. At first, it sounds simple, but depending on the approach you use, there are multiple ways to solve this. As someone who has been writing Python code for more than 10 years, I’ve faced this requirement … Read more >>
While cleaning a dataset for a project, I ran into an issue where my Python list had a mix of numbers and NaN values. If you’ve worked with real-world data in the US, say, sales reports, healthcare data, or survey results, you know how common missing values can be. The problem is simple: NaN (Not … Read more >>
