Question

我有两个问题和答案，它们都是列表，每个都包含3个字符串。我必须通过功能render_responses()

在终端中同时渲染两者

我尝试了下面显示的代码，但所有尝试似乎都失败了

QUESTIONS = [
  'Please explain your Python, Django and Django Rest Framework experience.',
  'What is your favorite feature of Python 3 and when did you use it?',
  'What is the most annoying aspect of Django or DRF?'
]

# TODO: Add your answers
ANSWERS = ["I took 2 classes through university both which were taught in python.", "me", "bee"]

def render_responses(questions, answers):
  # TODO: Render your responses out to the console
  questions = QUESTIONS
  answers = ANSWERS
  if questions == []:
    return("There are no questions")
  elif answers == []:
    return("There are no answers")
  else:
    return(questions[0], answers[0], questions[1], answers[1], questions[2], answers[2])

代码可以编译，但仅在我放置print（render_responses）时返回<函数render_responses于0x7fa2b1942b70>

Answer 1

重要的是要注意，在python中，几乎所有东西都是对象。包括功能。 render_responses是一个函数对象，您可以在此行上打印它：

print(render_responses)

如果您想调用该函数，请在其后加上括号并为其提供必要的参数：

print(render_responses(questions, answers))

Answer 2

您不是在调用函数，只是在打印名称和有关该函数的一些元数据。

使用

print(render_responses())

为什么这段代码不呈现我输入的问题和答案？
