SQL And Python Mistakes To Avoid - Issue 155

Don’t repeat my mistakes. Learning from common errors and how to avoid them

The painful part of growing up is accepting your mistakes, errors, and missteps. We all do them, learn from them, embrace the shame, and move forward. That’s how you know you are growing - with every step you take, you can remember 1 or 2 mistakes you made to get here. 

If you are in a leadership position, it’s your responsibility to ensure that you will be able to contain, own, and ideally prevent whatever errors your team makes.

Today I’ll grudgingly share some painful lessons I learned from my own errors made while working with SQL and Python to extract, read, and analyze data. These mistakes are so simple and basic, which makes it that much harder to accept. I hope it will remind us of the importance of triple-checking, code reviews, and cross-team validation.
