# Python Program to Sort a List in Descending Order

###### Tutorialsrack 04/05/2020 Python

In this python program, we will learn how to sort a list in descending order. There are various ways to sort a list in descending order in python. We can sort the list using python built-in functions such as using `sort()`, `sorted()`, `sort()` and `reverse()` or using loops.

Here is the source code of the program to sort a list in descending order.

### Program 1: Python Program to Sort a List in Descending Order Using sort() with option reverse=True Method

In this program, we used the python built-in `sort()` function with option `reverse=True`. The `sort()` function sorts the list and `reverse=True` reverse the sorted list in descending order.

##### Python Program to Sort a List in Descending Order Using sort() with option reverse=True Method
``````# Python Program to Sort a List in Descending Order Using sort()
# with option reverse=True Method

NumList = [12,45,87,49,56,46]

# Print the List
print("\nElement Before Sorting is: ", NumList)

NumList.sort(reverse=True)
print("\nElement After Sorting List in Descending Order is:\n", NumList)
``````
##### Output

Element Before Sorting is:  [12, 45, 87, 49, 56, 46]

Element After Sorting List in Descending Order is:

[87, 56, 49, 46, 45, 12]

### Program 2: Python Program to Sort a List in Descending Order Using sorted() with option reverse=True Method

In this program, we used the `sorted()` function to sort the list using `reverse=True` option. The `sorted()` function sort the list and `reverse=True` reverse the list in descending order.

##### Python Program to Sort a List in Descending Order Using sorted() with option reverse=True Method
``````# Python Program to Sort a List in Descending Order Using sorted()
# with option reverse=True Method

NumList = [12,45,87,49,56,46]

# Print the List
print("\nElement Before Sorting is: ", NumList)

new_NumList=sorted(NumList,reverse=True)
print("\nElement After Sorting List in Descending Order is: \n", NumList)
``````
##### Output

Element Before Sorting is:  [12, 45, 87, 49, 56, 46]

Element After Sorting List in Descending Order is:

[12, 45, 87, 49, 56, 46]

### Program 3: Python Program to Sort a List in Descending Order Using sort() and reverse() Method

In this program, we used the python built-in function `sort()` and `reverse()`. The `sort()` function sorts the list in ascending order and the `reverse()` function reverses the list in descending order.

##### Python Program to Sort a List in Descending Order Using sort() and reverse() Method
``````# Python Program to Sort a List in Descending Order Using sort() and reverse() Method

NumList = [12,45,87,49,56,46]

# Print the List
print("\nElement Before Sorting is: ", NumList)

NumList.sort()
NumList.reverse()
print("\nElement After Sorting List in Descending Order is: \n", NumList)
``````
##### Output

Element Before Sorting is:  [12, 45, 87, 49, 56, 46]

Element After Sorting List in Descending Order is:

[87, 56, 49, 46, 45, 12]

### Program 4: Python Program to Sort a List in Descending Order Using For Loop

##### Python Program to Sort a List in Descending Order Using For Loop
``````# Python Program to Sort a List in Descending Order Using For Loop

NumList = [12,45,87,49,56,46]

# Print the List
print("\nElement Before Sorting is: ", NumList)

Number=len(NumList)
for i in range (Number):
for j in range(i + 1, Number):
if(NumList[i] < NumList[j]):
temp = NumList[i]
NumList[i] = NumList[j]
NumList[j] = temp

print("\nElement After Sorting List in Descending Order is: \n", NumList)
``````
##### Output

Element Before Sorting is:  [12, 45, 87, 49, 56, 46]

Element After Sorting List in Descending Order is:

[87, 56, 49, 46, 45, 12]

### Program 5: Python Program to Sort a List in Descending Order Using While Loop

##### Python Program to Sort a List in Descending Order Using While Loop
``````# Python Program to Sort a List in Descending Order Using While Loop

NumList = [12,45,87,49,56,46]

print("\nElement Before Sorting is: ", NumList)
Number=len(NumList)

i = 0
while(i < Number):
j = i + 1
while(j < Number):
if(NumList[i] < NumList[j]):
temp = NumList[i]
NumList[i] = NumList[j]
NumList[j] = temp
j = j + 1
i = i + 1

print("\nElement After Sorting List in Descending Order is: \n", NumList)
``````
##### Output

Element Before Sorting is:  [12, 45, 87, 49, 56, 46]

Element After Sorting List in Descending Order is:

[87, 56, 49, 46, 45, 12]
