编写一个 Python 程序,按照降序对列表项进行排序。在这个 Python 示例中,我们使用列表排序和反向方法对列表进行降序排序。
intlist = []
intlistTot = int(input("Total Number of List Items to Sort = "))
for i in range(1, intlistTot + 1):
intlistvalue = int(input("Please enter the %d List Item = " %i))
intlist.append(intlistvalue)
intlist.sort()
intlist.reverse()
print('List Items After Sorting in Descending Order')
print(intlist)
在这个 Python 程序中,我们使用了嵌套 for 循环和 temp 变量对列表项进行降序排序。
intlist = []
intlistTot = int(input("Total Number of List Items to Sort = "))
for i in range(1, intlistTot + 1):
intlistvalue = int(input("Please enter the %d List Item = " %i))
intlist.append(intlistvalue)
for i in range(len(intlist)):
for j in range(i + 1, len(intlist)):
if(intlist[i] < intlist[j]):
temp = intlist[i]
intlist[i] = intlist[j]
intlist[j] = temp
print('List Items After Sorting in Descending Order')
for i in range(len(intlist)):
print(intlist[i], end = ' ')
Total Number of List Items to Sort = 8
Please enter the 1 List Item = 17
Please enter the 2 List Item = 47
Please enter the 3 List Item = 12
Please enter the 4 List Item = 99
Please enter the 5 List Item = 55
Please enter the 6 List Item = 4
Please enter the 7 List Item = 60
Please enter the 8 List Item = 75
List Items After Sorting in Descending Order
99 75 60 55 47 17 12 4
Python 程序,使用 while 循环按降序对列表项进行排序。
intlist = []
intlistTot = int(input("Total Number of List Items to Sort = "))
i = 1
while(i <= intlistTot):
intlistvalue = int(input("Please enter the %d List Item = " %i))
intlist.append(intlistvalue)
i = i + 1
i = 0
while(i < len(intlist)):
j = i + 1
while j < len(intlist):
if(intlist[i] < intlist[j]):
temp = intlist[i]
intlist[i] = intlist[j]
intlist[j] = temp
j = j + 1
i = i + 1
print('List Items After Sorting in Descending Order')
i = 0
while(i < len(intlist)):
print(intlist[i], end = ' ')
i = i + 1
Total Number of List Items to Sort = 7
Please enter the 1 List Item = 19
Please enter the 2 List Item = 55
Please enter the 3 List Item = 89
Please enter the 4 List Item = 32
Please enter the 5 List Item = 47
Please enter the 6 List Item = 15
Please enter the 7 List Item = 7
