This program will not work in python 3.6 I can not figure out how to re- type it so it works in python 3.6

Explanation / Answer

There were two bugs in your code. One was in readFile method it was not reading file word ny word I changed that mehod. Other bug was in getMedian method where divide operator was wrong.I'm posting working code below with comments:

import sys
def readFile(filename): # readFile method was not working.You should read file word by word
numbers = []
with open(filename,'r') as f:
for line in f:
for word in line.split():
print(word)
numbers.append(int(word))
return numbers
def getSum(ar):
sum=0
for number in ar:
sum = sum + int(number)
return sum
def getCount(ar):
count=0
for num in ar:
count = count + 1
return count

def getAverage(ar):
avg= float(getSum(ar))/float(getCount(ar))
return avg
def getMax(ar):
maximum = ar[0]
for num in ar:
if num > maximum:
maximum = num

return maximum
def getMin(ar):
minimum = ar[0]
for num in ar:
if num < minimum:
minimum = num
return minimum

def getRange(ar):
maxim = getMax(ar)
minim = getMin(ar)
return maxim - minim
def sort(ar):
length =getCount(ar)
i = 0
j = 0
while i < length:
j=0
while j<length -1:
if ar[j] > ar[j+1]:
temp = ar[j+1]
ar[j+1] = ar[j]
ar[j] = temp
j=j+1
i=i+1

def getMedian(ar):
sort(ar)
length = getCount(ar)

if length % 2 is 0 :
return (ar[length//2 - 1])+ float(ar[length//2])/2.0 #return was wrong. Divide operator should be //
return ar[length//2] # same here

def getMode(ar):
sort(ar)
length = getCount(ar)
maxim = 1
mode = []
if length is 1 or 0:
if length is 1:
mode.append(str(ar[0]))
return mode
else:
return mode
i = 0
count = 1
while i < length-1:
if ar[i] != ar[i+1]:
count=1;
else:
count = count + 1
if count > maxim:
maxim = count
i = i + 1
if ar[i] == ar[i-1]:
count = count + 1
if count > maxim:
maxim = count
i = 0
count = 1
while i < length-1 :
if ar[i] != ar[i+1]:
count=1;
else:
count = count + 1
if count == maxim:
mode.append(str(ar[i]))
i = i + 1

if ar[i] == ar[i-1]:
count = count + 1
if count == maxim:
mode.append(str(ar[i]))
return mode

choice = 'y'
while choice is 'y' :
filename =""
try:
filename=input("Enter File Name: ")

array = readFile(filename)
except IOError:
print ("Invalid file name ",filename)
choice = input("Would you like to evaluate another file? (y/n): ")
continue
count = getCount(array)
if count is 0:
print ("There are no numbers in ",filename)
choice = input("Would you like to evaluate another file? (y/n): ")
continue
sum = getSum(array)

average = getAverage(array)

print ("Count: ",count)
print ("Average: ",average)
print ("Maximum: ", getMax(array))
print ("Minimum: ", getMin(array))
print ("Range: ",getRange(array))
