Answer 1

第一个改进应该是for-loop。

for i in range(12):
    print '$',savings[i], '\t','\t', '$',notGreenCosts[i], '\t','\t', '$',goneGreenCosts[i], '\t','\t', months[i]

Answer 2

#The function displayInfo will display the savings,
#the costs prior to going green, the costs after
#going green for the appropriate months

def displayInfo (notGreenCosts, goneGreenCosts, savings, months):
    print
    print '\t' '\t' '\t' 'SAVINGS'
    print '___________________________________________________________'
    print 'SAVINGS' '\t''\t' 'NOT GREEN' '\t' 'GONE GREEN' '\t' 'MONTH'
    print '-----------------------------------------------------------'
    for i in range(12):  
      print '$',savings[i], '\t','\t', '$',notGreenCosts[i], '\t','\t', '$',goneGreenCosts[i], '\t','\t', months[i]

有没有更好的方法来编写python中的这个
