python - NameError:名称 '' 未定义

Question

我正在尝试用 Python 编写一个脚本来结合西类牙语动词。这是我第一次使用 Python 编写脚本，所以这可能是一个简单的错误。当我运行脚本时，我输入“yo tener”并收到错误:

Traceback (most recent call last): File "", line 13, in File "", line 1, in NameError: name 'yo' is not defined

  # Input pronoun and verb for conjugation.
  text = raw_input()
  splitText = text.split(' ')
  conjugateForm = eval(splitText[0]) 
  infinitiveVerb = eval(splitText[1]) 
  
  # Set the pronouns to item values in the list.
  yo = 0
  nosotros = 1
  tu = 2
  el = 3
  ella = 3
  usted = 3
  
  # Conjugations of the verbs.
  tener = ["tengo", "tenemos", "tienes", "tiene", "tienen"]
  ser = ["soy", "somos", "eres", "es", "son"]
  estar = ["estoy", "estamos", "estas", "esta", "estan"]
  
  # List of all of the infinitive verbs being used. Implemented in the following "if" statement.
  infinitiveVerbs = [tener, ser, estar]
  
  # Check to make sure the infinitive is in the dictionary, if so conjugate the verb and print.
  if infinitiveVerb in infinitiveVerbs:
      print("Your conjugated verb is: " + infinitiveVerb[conjugateForm])

当您使用eval()时函数，您将其参数作为 Python 语句进行评估。我认为这不是您想要做的...

如果您尝试将代词放入 conjugateForm 变量中，并将动词放入 infinitiveVerb 变量中，只需使用:

conjugateForm, infinitiveVerb = text.split()

默认情况下，split() 按空格进行拆分，因此不需要 ' '。
