Local Computer vs Workspace

# The dictionary will be something like:
# {'Jason Seifer': ['Ruby Foundations', 'Ruby on Rails Forms', 'Technology Foundations'],
#  'Kenneth Love': ['Python Basics', 'Python Collections']}
#
# Often, it's a good idea to hold onto a max_count variable.
# Update it when you find a teacher with more classes than
# the current count. Better hold onto the teacher name somewhere
# too!
#
# Your code goes below here.

So I have two sets of code, one that passes on treehouse, 
but fails on my local computer and one that passes 
on my local computer and fails on workspace.

I am wondering if anyone knows why this is happening?"""
