NameError:名称“"未定义

问题描述

我正在尝试用Python编写一个脚本来结合西班牙语动词.这是我第一次使用Python编写脚本，因此这可能是一个简单的错误.运行脚本时，我输入"yo tener"并收到错误:

I am trying to make a script in Python that will conjugate Spanish verbs. This is my first time scripting with Python, so it may be a simple mistake. When I run the script, I input "yo tener" and receive an error:

  # 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])
  

推荐答案

使用 eval() 函数，您正在将其参数评估为Python语句.我不认为那是你想要做的...

When you use the eval() function, you're evaluating its arguments as a Python statement. I don't think that's what you want to do...

如果您试图将代词添加到conjugateForm变量中，并将动词添加到infinitiveVerb变量中，只需使用:

If you're trying to get the pronoun into the conjugateForm variable, and the verb into the infinitiveVerb variable, just use:

conjugateForm, infinitiveVerb = text.split()

默认情况下，split()在空白处分割，因此' '不是必需的.

By default, split() splits on whitespace, so the ' ' isn't necessary.
