python for loop

Question

I want to order the numbers of list from the lowest to highest but the program occurs with error that ((Traceback (most recent call last):
File "C:/Users/PycharmProjects/untitled2/3.py", line 10, in <module>
if b[i] > b[i + 1]:
IndexError: list index out of range))
how can i fix this problem??!!
what is the wrong with it

print("please enter 5 numbers : ")
b = []
for i in range(5):
a = input()
a = int(a)
b.append(a)

for i in range(0, 5):
for j in range(0, 5):
if b[i] > b[i + 1]:
temp = b[i]
b[i] = b[i + 1]
b[i + 1] = temp

Answer 1

Your sorting "algorithm" is wrong and will not sort...try:-

for i in range(len(b)-1, 0, -1):
for j in range(i):
if b[j] > b[j + 1]:
b[j], b[j + 1] = b[j + 1], b[j]

Answer 2

Hi. Error message has already said enough. Just look at this i+1, at the point when i is 4 this expression gives 5, but the last item of array from 5 elements has index 4.
So you should run second loop one less time

Answer 3

Tnx very much thats true
