This is a small meal planner written in Python.

MealPlanner.py

# This is a meal planner to help me decide what to eat for dinner.  I don't like to 
# waste a lot of time thinking about what to cook, so this would ideally help me create a 
# varied menu without too much deliberation.

invalid syntax (, line 56)
I got this error. Thanks in adv.

@monojudemy This code is written for Python 2. I suspect the syntax error on line 56 is because you are using a Python 3 interpreter.
