Ecco qualcosa I whipp ed up (per risolvere lo stesso tipo di problema). L'ho controllato solo con le mie ultime versioni di Python installato (OS X). Le parti di importazione sotto ci sono le (clunkily-nome) chiavi di ordinamento: sortKeyWithTwoListOrders e sortKeyWith2ndThen1stListValue
#Tested under Python 2.7.1 & Python 3.2.3:
import random # Just to shuffle for demo purposes
# Our two lists to sort
firstCol=['abc','ghi','jkl','mno','bcd','hjk']
secondCol=[5,4,2,1]
# Build 2 dimensional list [[firstCol,secondCol]...]
myList = []
for firstInd in range(0, len(firstCol)):
for secondInd in range(0, len(secondCol)):
myList = myList + [[firstCol[firstInd],secondCol[secondInd]]]
random.shuffle(myList)
print ("myList (shuffled):")
for i in range(0,len(myList)):
print (myList[i])
def sortKeyWithTwoListOrders(item):
return secondCol.index(item[1]), firstCol.index(item[0])
myList.sort(key=sortKeyWithTwoListOrders)
print ("myList (sorted according to strict list order, second column then first column):")
for i in range(0,len(myList)):
print (myList[i])
random.shuffle(myList)
print ("myList (shuffled again):")
for i in range(0,len(myList)):
print (myList[i])
def sortKeyWith2ndThen1stListValue(item):
return item[1], item[0]
myList.sort(key=sortKeyWith2ndThen1stListValue)
print ("myList (sorted according to *values*, second column then first column):")
for i in range(0,len(myList)):
print (myList[i])
