for loop - Error when attempting to call an index from a list in python -


i'm trying make function print data_sets[51] huge list. when try run error:

line 460, in paste_up items in sublist[1]: indexerror: list index out of range

my function paste_up looks this:

# paste sheets onto billboard per provided data set def paste_up(data):    sublist in data_sets:        items in sublist[1]:         if item[0] == 'sheet a':             sheet_a( item[1], item[2])         elif item[0] == 'sheet b':             sheet_b( item[1], item[2])         elif item[0] == 'sheet c':             sheet_c( item[1], item[2])         elif item[0] == 'sheet d':             sheet_d( item[1], item[2])

the list i'm trying test is:

['x', ['sheet a', 'location 1', 'upright'],           ['sheet b', 'location 2', 'upright'],           ['sheet c', 'location 3', 'upright'],           ['sheet d', 'location 4', 'upright']],

any appreciated.

edit..... having issues function endlessly drawing images trying print. here example of function draws 200x500 rectangle @ specific location.

#draw sheets , images on them. def sheet_a(location, orientation):     #code location , orientation of sheet_a.     if location == 'location 1':         if orientation == 'upright': goto(-300,0);setheading(0)         elif orientation == 'upside down': goto(-300,0);setheading(180)      elif location == 'location 2':         if orientation == 'upright':goto(-100,0);setheading(0)         elif orientation =='upside down': goto(-100,0);setheading(180)      elif location == 'location 3':         if orientation == 'upright':goto(100,0);setheading(0)         elif orientation == 'upside down':goto(100,0);setheading(180)      elif location == 'location 4':             if orientation == 'upright':goto(300,0);setheading(0)         elif orientation == 'upside down':goto(300,0);setheading(180)      #drawing sheet_a outline , filling background.     width(3);penup();begin_fill();forward(100);pendown();right(90)     forward(250);right(90);forward(200);right(90);forward(500);right(90)     forward(200);right(90);forward(250);color('blue');end_fill();color('black');penup()

first of change for items... for item...

and code should like:

for sublist in data_sets:     item in sublist[1:]:         if item[0] == 'sheet a':             sheet_a( item[1], item[2])         elif item[0] == 'sheet b':             sheet_b( item[1], item[2])         elif item[0] == 'sheet c':             sheet_c( item[1], item[2])         elif item[0] == 'sheet d':             sheet_d( item[1], item[2])

it should work if data looks this:

data_sets = [['x',   ['sheet a', 'location 1', 'upright'],   ['sheet b', 'location 2', 'upright'],   ['sheet c', 'location 3', 'upright'],   ['sheet d', 'location 4', 'upright']]]
