python - TypeError, When calculating variables from a dictionary -


what type val_dict.get(filename)[1]? keep getting typeerror, telling me nonetype: 

typeerror: unsupported operand type(s) *: 'float' , 'nonetype'

when try run script line :

water = (float(x1[count]) * (val_dict.get(filename[1]))

i keep getting errors. i've tried calling float, int , str, didn't help.

i've written script import values excel-spreadsheet , scale them. after script supposed extract these values new excel spreadsheet, , thought easiest way storing data in dictionary looks this:

        val_dict[filename] = [model, lenghtvalue, dispvalue, froudemax, froudemin]  return val_dict  val_dict = locate_vals() print val_dict #output: {'c:/eclipse/tst-folder\\test spreadsheet model 151b wl3.xls': [u'm151b', 14.89128, 316.29, 1.0, 0.4041900066850382], 'c:/eclipse/tst-folder\\foldera\\test spreadsheet model 151 wl1 lastet.xls': [u'm151', 14.672460000000001, 316.28887, 1.0, 0.4041900066850382]}

in case interesting, x1-list's output looks this:

[0.35714285714285715, 0.35714285714285715] [1.5845602477694463e-07, 1.5845602477694463e-07]

the issue line:

water = (float(x1[count]) * (val_dict.get(filename[1]))

which should be:

water = (float(x1[count]) * (val_dict.get(filename)[1]))

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
