Highlights

PYTHON TEACHER COFFEE MUG | Funny Coding Instructor Mug for CS Teachers & Programming Educators

>>> class = "Python 101"
SyntaxError: invalid syntax
# 'class' is a reserved word.
# So is my coffee break.

A funny coffee mug for Python teachers, coding instructors, and computer science educators! The design shows a real Python error: you can't use "class" as a variable name, because it's reserved for defining actual classes. This mug jokes that the teacher's coffee break is just as off-limits.

THE JOKE, EXPLAINED
In Python, "class" is a reserved keyword used to define new object types, so you're never allowed to reuse it as a variable name. This mug compares that rule to a teacher's coffee break: also reserved, also non-negotiable!

PERFECT GIFT FOR
- Python teachers, coding instructors and CS professors
- Bootcamp instructors and coding camp educators
- Teaching assistants and STEM teachers
- Any teacher who will appreciate the classroom pun
- Teacher appreciation week, end of semester, and holiday gifts

DESIGN
- Dark code-editor style panel with colorful syntax highlighting
- A real Python error message with a classroom-themed example
- Sits on a clean white ceramic mug
