cs50 Pythonの貪欲 - 解析中のEOF？

Question

私はこのエラーが発生して以来私のプログラムを実行することはできませんが、GreedyをCからPython（Pythonの新人初心者）に変換しようとしています：SyntaxError： 私はここや他のところでいくつかの答えを見てきましたが、私のコードでそれを取り除くことはできませんでした。助けてください。 他の論理エラーの入力も大好きです。

#!usr/bin/python3 
'''CS50- Greedy programme in C translated to Python''' 
import math 

def main(): 
    print("welcome to the change game!") 

#prompt user for change 
change = float(raw_input("enter change as x.xx: ")) 
if (change < 0 or change == 0): 
    print("change must be a positive number:") 
elif not isinstance(change, float): 
    print("change must be a positive number: ") 
else: 
    break 

change = round(change * 100) 
#determine different coin usage 
quar = changeCal(change, 25) 
dime = changeCal(change, 10) 
nick = changeCal(change, 5) 
penn = changeCal(change, 1) 

#verify functions correctness and print 
if (change == 0): 
    print("{}".format(quar+dime+nick+penn)) 
    return 0 
else: 
    print("couldn't process") 
    return 1 

def changeCal(change, n): 
#calc. change/subtraction 
    i = 0 

if (change >= 0): 
    for i in range(change, n, 1): 
     change = (change - n) 
    return i

は、いくつかの変更を働いたと誰もが興味を持っていた場合、それを動作するように管理します。 ！
