Write a Python program to sort list items in descending order. In this example, we used the sort and reverse methods to sort the list in descending order.
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)
In this Python program, we used the nested for loops and temp variables to sort the Python list items in descending order.
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 This program helps to sort list items in descending order using a while loop.
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('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
Descending Order
89 55 47 32 19 15 7 By default, the built-in sort() function sorts a list of strings in alphabetical order. So, if we use the sort() function with the reverse argument, it sorts strings from Z to A. Refer to Python sort.
holidays = ['kerala', 'London', 'Amsterdam', 'Rome']
holidays.sort(reverse=True)
print(holidays)
['kerala', 'Rome', 'London', 'Amsterdam']If the task is to sort the string items in descending order based on their length (word count), add the key argument with the len() function. Refer to Python len.
holidays = ['kerala', 'London', 'Amsterdam', 'Rome']
holidays.sort(reverse=True, key= len)
print(holidays)
['Amsterdam', 'kerala', 'London', 'Rome']Also Read
