The Scoop

4 Debugging Techniques You Can Use Right Now

Print and Log Smartly
Forget scattershot console logs. Structure your output, use log levels, and know when to remove them so your debugging stays clear and efficient.

Use the Debugger, Not Just Prints
Step through your code line by line. Modern IDEs like VS Code and PyCharm offer breakpoints, watches, and stack inspection that reveal what’s happening under the hood.

Reproduce Before You Fix
Always recreate the bug in a controlled environment. This not only confirms the issue but prevents “fixes” that introduce new problems.

Immediate Error Checking
With assert, you specify a condition that must be true. If it is not, your program raises an AssertionError and stops right there.
