Question

allData is a hash table. key values are product numbers. the value is a list of tuples. The first value in the tuple is either 0,1,2,3 and the second value of the tuple is a list of errors for that number.

print len(allData[modelNumber][0][1]) #compiles fine

File "burninprocessor.py", line 467
   bars = [len(allData[modelNumber][0][1]), len(allData[modelNumber][1][1], len(allData[modelNumber][2][1], len(allData[modelNumber][3][1])]
                                                                                                                                        ^

Answer 1

You have no closing parentheses on the second and third term in your 4-tuple. Try (split across lines for readability here but you probably want to keep it on one line in your code):

bars = [len(allData[modelNumber][0][1]), len(allData[modelNumber][1][1]),
        len(allData[modelNumber][2][1]), len(allData[modelNumber][3][1])]
