In this Python program, we will learn how to sort a list in ascending order. In this program, for sorting a list we used the python built-in function such as sort(), sorted() and without using the sorting function.
Here is the source code of the program to sort a list in ascending order.
In this program, we used the python built-in function sort() to sort the list in ascending order by default.
The sort() function takes two parameters:
reverse = the first parameter is optional.if reverse = True then it returns a sorted list in descending order.
Key = second Parameter. It is also optional and this function used to specify the sorting criteria(s)
# Python Program to Sort a List in an Ascending Order Using sort() Method
NumList = [12,45,87,49,56,46]
# Print the List
print("\nElement Before Sorting is: ", NumList)
NumList.sort()
print("\nElement After Sorting List in Ascending Order is: \n", NumList)
Element Before Sorting is: [12, 45, 87, 49, 56, 46]
Element After Sorting List in Ascending Order is:
[12, 45, 46, 49, 56, 87]
In this program, we used the python built-in sorted() function to sort the list in ascending order. Python lists have a built-in sorted() function that builds a new sorted list from an iterable. sorted() have a key parameter to specify a function to be called on each list element prior to making comparisons.
# Python Program to Sort a List in an Ascending Order Using sorted() Method
NumList = [12,45,87,49,56,46]
# Print the List
print("\nElement Before Sorting is: ", NumList)
new_NumList=sorted(NumList)
print("\nElement After Sorting List in Ascending Order is: \n", new_NumList)
Element Before Sorting is: [12, 45, 87, 49, 56, 46]
Element After Sorting List in Ascending Order is:
[12, 45, 46, 49, 56, 87]
# Python Program to Sort a List in an Ascending 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 Ascending Order is: \n", NumList)
Element Before Sorting is: [12, 45, 87, 49, 56, 46]
Element After Sorting List in Ascending Order is:
[12, 45, 46, 49, 56, 87]
# Python Program to Sort a List in Ascending Order Using While Loop
NumList = [12,45,87,49,56,46]
# Print the List
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 Ascending Order is: \n", NumList)
Element Before Sorting is: [12, 45, 87, 49, 56, 46]
Element After Sorting List in Ascending Order is:
[12, 45, 46, 49, 56, 87]
