How to find minimum and maximum among a list of integers in Python without using built-in functions from console

Question

In the following code, I am unable to accept the input list values from console.

    s=[]
for i in range(10):
    s[i]=int(input('enter integers from 1 to 10\n'))


mini=11
for temp in s:
    if mini>temp:
            mini=temp
print('minimum : '+str(mini))

maxi=0
for temp in s :
    if maxi<temp:
        maxi=temp
print('maximum :'+str(maxi))

IndexError : list argument index out of range.

Cant find where index went out of range.Please help, thanks in advance.

Your error has nothing to do with the title (a homework?). It is ok to ask about specific issues with your code and you should *mention the context* but *don't put it in the title*. You could change the title: "IndexError while reading a list of integers". Provide only relevant parts of the code (drop everything after the error line); include the *full* traceback. Please, limit your questions to one issue per question (you could include links to related questions for context). — jfs, Jul 16 '15 at 11:28
I am a novice programmer in Python.its not homework, but making trail and error method for learning to code sir, I will make a note of your points definitely. — Vikranth Inti, Jul 16 '15 at 11:31

You should be appending, you cannot index an empty list so s[i] will fail straight away with s[0] as the list is empty:

s = []
for i in range(10):
   s.append(int(input('enter integers from 1 to 10\n')))

mini,maxi = 0, 11
for temp in s:
    if temp < mini:
        mini = temp
    if temp > maxi:
        maxi = temp
print('minimum : '+str(mini))
print('maximum :'+str(maxi))

You can also check the two in a single loop as above instead of doing two iterations over s.

You can also use a list compt to create your list of numbers:

s = [int(input('enter integers from 1 to 10\n')) for _ in range(10)]

list compt seems a very simple way of doing the job.Thanks – Vikranth Inti Jul 16 '15 at 11:18
@VikranthInti, yep, just be aware that the code would break for any bad input from the user, in the real world you would validate the input from the user – Padraic Cunningham Jul 16 '15 at 11:19
ok, I am novice in coding..so these might seem silly questions, but I am learning .ty – Vikranth Inti Jul 16 '15 at 11:27
No worries, I figured that. – Padraic Cunningham Jul 16 '15 at 11:31

you should append to the list.

s=[]
for i in range(10):
    s.append(int(input('enter integers from 1 to 10\n')))


mini=11
for temp in s:
    if mini>temp:
        mini=temp
print('minimum : '+str(mini))

maxi=0
for temp in s :
    if maxi<temp:
        maxi=temp
print('maximum :'+str(maxi))
