Daily Software Tips & Tricks

When you need to transform a list in Python, don't default to a bulky for-loop. A list comprehension like [x.upper() for x in words if len(x) > 3] is often more readable and idiomatic. However, the senior dev secret is knowing when to stop: if your comprehension is stretching across multiple lines or involves complex nested logic, it’s usually better to revert to a standard loop. Readability always wins over cleverness in a shared codebase.
