【问题描述】：

这是我的代码：

def checking():

  response2 = requests.get('https://www.nitrxgen.net/md5db/' + str(word[1])).text  

  if response2:
   print(Fore.GREEN + "[" + Fore.WHITE + strftime("%H:%M:%S")+ Fore.GREEN + "]" + Fore.WHITE + " |" + Fore.GREEN + " ■ " + Fore.WHITE +
    "Hash Found: " + Fore.GREEN + response2 + Style.RESET_ALL + "\n", end='')

  else:
   print(Fore.RED + "[" + Fore.WHITE + strftime("%H:%M:%S")+ Fore.RED + "]" + Fore.WHITE + " |" + Fore.RED + " ■ " + Fore.WHITE +
    "Hash Not Found" + Style.RESET_ALL + "\n", end='')

def Mutiple():

  Tk().withdraw() 
  filename = askopenfilename(title='Choose a File', filetypes=[("Text Files", "*.txt")])
  clear = lambda: os.system('cls')
  clear() 
  with open(filename, "r", encoding="utf8") as file:  
    for line in file:
        word = line.strip()
        word = word.split(":")
        return checking()

错误码是

Traceback (most recent call last):   
  File "C:\Users\tosun\OneDrive\Desktop\Hashkiller\Hashkiller.py", line 111, in <module>
    Mutiple()   
  File "C:\Users\tosun\OneDrive\Desktop\Hashkiller\Hashkiller.py", line 40, in Mutiple
    return checking()   
  File "C:\Users\tosun\OneDrive\Desktop\Hashkiller\Hashkiller.py", line 18,  in checking
    response2 = requests.get('https://www.nitrxgen.net/md5db/' + str(word[1])).text 
NameError: name 'word' is not defined

【问题讨论】：

return 语句真的应该在for 循环内吗？它只会处理文件的第一行。
另外，checking() 不会返回任何内容。 return checking() 应该返回什么？
给定的“重复”对于这个问题来说有点矫枉过正，但我希望它能解决您的问题，并且您可能还会遇到更多问题。

【解决方案1】：

word 是Mutiple() 中的局部变量。如果你想在checking()中使用它，你应该把它作为参数传递。

def checking(word):

  response2 = requests.get('https://www.nitrxgen.net/md5db/' + str(word[1])).text  

  if response2:
   print(Fore.GREEN + "[" + Fore.WHITE + strftime("%H:%M:%S")+ Fore.GREEN + "]" + Fore.WHITE + " |" + Fore.GREEN + " ■ " + Fore.WHITE +
    "Hash Found: " + Fore.GREEN + response2 + Style.RESET_ALL + "\n", end='')

  else:
   print(Fore.RED + "[" + Fore.WHITE + strftime("%H:%M:%S")+ Fore.RED + "]" + Fore.WHITE + " |" + Fore.RED + " ■ " + Fore.WHITE +
    "Hash Not Found" + Style.RESET_ALL + "\n", end='')

def Mutiple():

  Tk().withdraw() 
  filename = askopenfilename(title='Choose a File', filetypes=[("Text Files", "*.txt")])
  clear = lambda: os.system('cls')
  clear() 
  with open(filename, "r", encoding="utf8") as file:  
    for line in file:
        word = line.strip()
        word = word.split(":")
        return checking(word)
