List comprehension/list creating loop in python 3.x -

i've been trying make loop or list comprension thingy following:

prints "please give me number of bread sold @ ", self.bakeryname[k], ":" prompts user number of break sold @ given bakery, , stores in list

"please give me number of [breadtype] sold at:" "the hungry baron": [here enter number] "the flying bulgarian": [here enter number] 

it's stored in list of integers starts @ first prompted value , ends @ last -||-.

the number of bakeries potentially infinite, there's 3 different types of bread.

i've dug myself hole function:

def soldbread(self):     amount = ((len(self.bakeryname))*3)     k = 0     j = 0     h = 0     = 0     while j < (len(self.breadtype)):             print("please give me number of",self.breadtype[k], "sold at:")             while < amount:                 self.breadsold.append(i)                 self.breadsold[i] = int(input(self.bakeryname[h]))                 j += 1                 h += 1                 += 1                 if k == 3:                     break                 else:                     while j >= len(self.bakeryname):                         k += 1                         print("please give me number of",self.breadtype[k], "soldat:")                         j = 0                         h = 0 

the function go 15'th type of bread (there's 5 bakeries in self.bakeryname >at moment<, atleast number accurate) complain "indexerror: list index out of range". i've tried bunch of "if"'s , "breaks"'s can't pull off.

the names etc. in code translated native language, eventual typos not in code.

# data bakeries = ['a','b','c'] breadtypes = ['flat','rye','white'] # output data results = {}  bakery in bakeries:     # line each bakery     print('how many of each type of bread %s: ' % bakery)      # python3 dict comprehension , generator     results[bakery] = {         breadtype: breadtypevalue breadtype, breadtypevalue         in ((bt, input('%s: ' % bt)) bt in breadtypes)     }  # wanna print that? bakery in results:     print('here different types of breads %s:' % bakery)     print(', '.join(['%s: %s' % (breadtype, number) breadtype, number in results[bakery].items()]))
