python bubble sort error

Question

I tried to write a bubble sort program which doesn't work

n = raw_input("enter no of elements to be added in array")

print 'enter elements for an array to be sorted'
arr = []

for i in range(n):
    p=raw_input("enter next element of array\n")
    arr.append(p)
for j in range (len(arr)-1):
    for k in range(len(arr)-j-1):
        if(arr[k]>arr[k+1]):
           temp=arr[k]
           arr[k]=arr[k+1]
           arr[k+1]=temp

print("the sorted array is")
print arr

for example if i enter input no as "10,9,8,7,6,5,4,3,2,1" the sorted array comes out to be "1,10,2,3,4,5,6,7,8,9" for array "639,541,854,45,8" the answer is "854,45,639,45,541"

Answer 1

your program should be like

  n = input("enter no of elements to be added in array")

  print 'enter elements for an array to be sorted'
  arr = []

  for i in range(n):
      p=input("enter next element of array\n")
      arr.append(p)
  for j in range (len(arr)-1):
       for k in range(len(arr)-j-1):
           if(arr[k]>arr[k+1]):
                temp=arr[k]
                arr[k]=arr[k+1]
                arr[k+1]=temp

  print("the sorted array is")
  print arr

you should check how 'input' and 'raw_input' works
