Question

我无法弄清楚为什么它会显示一个未解决的“自我”的参考资料。在form_head，form_body和form_foot位之后......它不允许Google Engine应用程序显示并正确运行。任何帮助都会有所帮助。

import webapp2

class MainHandler(webapp2.RequestHandler):
    def get(self):

这里你的代码正确缩进（据我所知）。

我已经更新了我之前的答案，以展示如何使用textwrap.dedent()删除多余的缩进，这些缩进通常需要使大型内联文本块与缩进代码混合更具可读性。另外，我修改了末尾附近的self.response.write()语句，以显示将多个文本变量值替换为长字符串的更简洁方法。

import textwrap
import webapp2

class MainHandler(webapp2.RequestHandler):
  def get(self):
    #web page sections
    form_head=textwrap.dedent('''
      <!DOCTYPE html>
      <html>
        <head>
          <meta charset="utf-8" />
            <link href='http://fonts.googleapis.com/css?family=Roboto' rel='stylesheet' type='text/css'>
            <link href="css/style.css" rel="stylesheet" type="text/css" />
        <title>Gamers R' Us Subscribing</title>
        </head>
        <body>''')

    form_body=textwrap.dedent('''
          <div class="maincontainer">
            <h1>Welcome to Gamers R' Us!</h1>
            <div id="bgimg">

              <div id="formbox">
