I have spent over a decade writing Python code, and if there is one mathematical concept that constantly pops up in technical interviews and algorithm design, it is the Fibonacci series. The Fibonacci sequence is a fascinating set of numbers where each number is the sum of the two preceding ones. Usually, it starts with … Read more >>
Working as a Python developer for over a decade, I have encountered countless scenarios where I needed to calculate growth, interest, or scaling. In my early days, I often fumbled with complex mathematical syntax, but Python makes exponentiation incredibly intuitive and powerful. Whether you are calculating compound interest for a savings account in New York … Read more >>
In my experience working as a Python developer, I have realized that the best way to learn a language is to use it for things that actually matter in real life. Last week, it was my niece’s birthday in New York, and instead of just sending a boring text, I decided to write a quick … Read more >>
I have noticed that the smallest details often cause the most confusion for beginners. One of those details is how the Python print() function handles the end of a line. By default, every time you call the print function in Python, it moves to a new line. This happens because of the end parameter, which … Read more >>

However, as humans, we prefer reading dates like “December 25, 2025, 10:00 AM,” which is why we use Python … Read more >>
I have found that “empty” variables are the leading cause of crashes. I remember once debugging a Python script that processed IRS tax forms. A single “None” value in a list of deductions caused the entire payroll run to fail. Checking if a variable is not empty in Python is a fundamental skill that separates … Read more >>
In my ten years of architecting Python solutions for data-heavy firms in Chicago, I have seen developers stumble over one specific concept: the “empty” number. In Python, strings can be empty (“”) and lists can be empty ([]), but a float is a numeric type. It always holds a value, even if that value represents … Read more >>
To print 2 decimal places in Python, we can use the Python str.format() method with “{:.2f}” as string and float as a number. Then call the Python print(), it will print the float with 2 decimal places.
In my experience of writing Python code for data analytics firms, I have hit the same wall many times. You try to combine a piece of text with a decimal number, and Python throws a “TypeError.“ It is a classic beginner mistake, but even seasoned pros occasionally forget that Python is a strongly typed language. … Read more >>
