A customer-name cleanup script looks fine until someone enters “José”, “Megan O’Connor”, or an emoji in a notes field. When you print the value, terminals, log files, and API payloads do not always show those characters the same way. I have used Python’s ascii() function most often while debugging text pulled from CSV files, APIs, and form … Read more >>
The Python any() function returns True when at least one item in an iterable is truthy, and False when none is, including when the iterable is empty. Pair it with a generator expression to ask “does anything here match?” in one line: I ran every example on this page on Python 3.12.5 in Command Prompt, … Read more >>
I often use the Python all() function in automation scripts that validate data before producing a report. For example, before a sales-report script emails a CSV file to a manager, I need to confirm that every required field exists, every amount is valid, and every employee record meets the rules. You could write several for … Read more >>
Python has no built-in repeat() function, and what you need depends on what you are repeating. To repeat code a fixed number of times, use for _ in range(n). To repeat it until something happens, use while True with a break, because Python has no repeat-until loop. To repeat a value, multiply it: “ab” * … Read more >>
Python has two division operators. / is true division and always returns a float, so 7 / 2 is 3.5 and even 8 / 4 is 2.0. // is floor division: it divides and then rounds down, so 7 // 2 is 3. The difference that catches people out is negative numbers, where -7 // … Read more >>
You have a folder full of sales reports, and you want a small script that reads the files, totals each region, and creates a clean summary. With Python, you can usually get that first useful version running quickly. With Java, you may write more setup code, but you gain a strong foundation for building larger, … Read more >>
You have a spreadsheet full of sales data, a folder of reports to rename, or an API that needs daily data collection. In projects like these, I usually reach for Python because I can build a useful automation script quickly and keep the code easy to maintain. But if I need to build a game … Read more >>
To create a void function in Python, write a normal def function and don’t return a value. Python has no void keyword, so a function that ends without return hands back None automatically. Add -> None to make that intent clear: I ran each script below with Python 3.12.5 in a Windows Command Prompt, and … Read more >>
When I start a Python automation project, I want to write code quickly, run it without friction, and catch errors before the script touches a real report or API. The editor I choose affects all three. A small CSV cleanup script needs very little setup, while a larger Django application needs stronger project tools. That … Read more >>
Python vs C# comes down to this: Python is shorter to write and rules AI and scripting, while C# is a compiled, statically typed .NET language that runs faster and powers enterprise apps and Unity games. Here’s one line of the same report in each: To keep this honest, I wrote one small sales report … Read more >>
