Let's see, the print is just "debug", it's not necessary in the program.
'row[0]' is the first element of the current row. Ex.: row = ['a', 'b', 'c', 'd'] - row[0] would be 'a' 'rates' is a dictionary, 'rates[row[0]]' would update the key row[0] in the dict with the 'value' I think that's it, right? 2014-08-30 22:37 GMT-03:00 Danny Yoo <d...@hashcollision.org>: > As the error message suggests, the problem might be near line 40. > > > Look at lines 40 and 41 in your program. > > print(rates[row[0]] + " / VALUE : " + str(value)) > rates[row[0]] = value > > Look at it very carefully, and try to explain to yourself what those > two lines mean. > > What do you _want_ to happen when those two statements execute? > > What does "row[0]" mean? > > What does "rates[row[0]]" mean? > > Do you notice something strange? >
