I'm new to python and I'm trying to write a selection sort code starting with the last digit and eventually working its way to the first but I'm getting an error that the index is out of range... anyone know what's wrong with my code?
inputfilename = raw_input("What is the name of the file to be sorted? ")
print("Warning the outputfile will be overwritten if it exists!")
outputfilename = raw_input("Input the name for the output file: ")
inputfile = open(inputfilename)
outputfile = open(outputfilename, 'w')
numberlist = map(int, inputfile)
i = (len(numberlist))
while ( i > int(1)):
m = i
j = i - 1
while (j > int(0)):
if (numberlist[j] > numberlist[m]):
m = j
j = j - 1
temp = numberlist
numberlist = numberlist[m]
numberlist[m] = temp
i = i -1
for number in numberlist:
outputfile.write(str(number) + "\n")
outputfile.close()
