No no, don't tell us what error you got! I love guessing games. I'm guessing
you got either a SyntaxError or a NameError.

>>> def python_allows_really_long_function_names_with_no_problem():
...     print "hello world"
... 
>>> python_allows_really_long_function_names_with_no_problem()
hello world
>>>
>>> ptyhon_allows_really_long_function_names_with_no_problem()
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
NameError: name 'ptyhon_allows_really_long_function_names_with_no_problem'
is not defined

Can you spot the difference? More importantly, can you see how the error
message actually tells you what the error is?
