ENVIRONMENT: Windows 7 Python2.7 Eclipse SDK 3.7.2

Trying to follow a tutorial from http://www.youtube.com/watch?v=Z-HpXbhVuGo I receive an error message:

SyntaxError:invalid syntax highlights the following line of code:(bestStudent[i] - stewiestudent
You have some non-ASCII quotes ’ mixed in with ASCII quotes '. Change all of the non-ASCII to ASCII and you should be fine. - mechanical_meat
I also see a backtick ` in there. You will also need to change that to an ASCII quote. - mechanical_meat

For the syntax error highlighting bestStudent[i] Replace that print statement with

print (bestStudent[i] + 'scored a ' + i) with ()

Also your code contains a lot of ‘ ’ instead of ' ' single-qoutes which you can simply replace

Fix those issues, I think it ought to work.

Non-ascii characters replaced: 

from __future__ import print_function

bestStudent = {}
f = open ("C:/Users/lenovo/workspace/assignment3/studentgrades.txt")
for line in f:
    name, grade = line.split()
    bestStudent[grade] = name

f.close()

bestStudentStr= "" 

for i in sorted(bestStudent.keys(), reverse=True):
    print bestStudent[i] + "scored a " + i
bestStudentStr += bestStudent[i] + " scored a " + i + "\n"

bestStudentStr = "\nThe Best Students Ranked\n\n" + bestStudentStr

print(bestStudentStr)

outToFile = open("studentrank.txt", mode="w", encoding="utf-8")
outToFile.write(bestStudentStr)

outToFile.close()

print("Finished update")

This happens when you copy source from pdf,doc etc file. The best solution is to copy/paste in a text editor without unicode support, you'll see then what wrong is as ? marks.
