PYTHON PROGRAMMER COFFEE MUG | Funny KeyError No Weekend Joke Mug for Developers & Coffee Lovers

>>> my_week['weekend']
KeyError: 'weekend'

A funny coffee mug for Python coders who never seem to get a day off! The design shows a real Python error, KeyError, that appears when the "weekend" key simply doesn't exist in the programmer's week.

THE JOKE, EXPLAINED
In Python, a dictionary stores items under names called keys, and a KeyError appears when you ask for a key that isn't there. This mug jokes that "weekend" is missing from the programmer's schedule entirely!

PERFECT GIFT FOR
- Python developers and software engineers
- Overworked coworkers, freelancers and startup teams
- Computer science students and bootcamp graduates
- Anyone who loves coffee and programming humor
- Birthdays, work anniversaries, Secret Santa and holidays

DESIGN
- Dark code-editor style panel with red error text and yellow highlights
- Looks like a real Python error message
- Sits on a clean white ceramic mug

PRODUCT FEATURES
- Glossy white ceramic with a comfortable C-handle
- Available in 11oz and 15oz
- Vibrant, crisp color printing

CARE INSTRUCTIONS
Clean in the dishwasher, or wash by hand with warm water and dish soap.
