TypeError：'NoneType'類型的參數是不可迭代的python

Question

我一直得到這個錯誤的像20「if ntext [x] in dictionary：」。該程序將文字說話轉換成英語。

import csv 
def CreateDictionary(): 
    fo = open("textToEnglish2014.csv" , "r") 
    dictonary = {} 
    reader = csv.reader(fo) 
    for row in reader: 
     dictionary[row[0]] = row[1] 
     return dictionary 

def main(): 
    dictionary = CreateDictionary() 
    y = "y" 
    while y == "y": 
     text = input("Enter text to which you would like conversion: ") 
     text = text.lower() 
     ntext = text.split(" ") 
     new_text = "" 
     x = 0 
     while x < len(ntext): 
      if ntext[x] in dictionary: 
       new_text = new_text + dictionary[ntext[x]] + " " 
      else: 
       export = export + "NF " 
      x += 1 
     print (new_text) 
     y = input("Continue conversion? y or q ") 

main() 

Answer 1

dictonary = {} 

應該

dictionary = {} 

注意拼寫
