主题:python语法入门中导入import与from时的代码示例
本文主要介绍的是在python语法入门中导入import与from时的相关代码的示例,如果你对python语法入门导入import与from的相关实际应用的相关内容的具体介绍,以下就是文章的主要内容 。
3. import wsgiref.handlers
4. from google.appengine.ext import db
5. from google.appengine.api import users
6. from google.appengine.ext import webapp
创建一个模块,相当于一个数据表,也相当于一个类
3. content = db.StringProperty(multiline=True)
4. date = db.DateTimeProperty(auto_now_add=True)
MainPage也是类吧,参数似乎是继承的意思
3. self.response.out.write(')
4. greetings = db.GqlQuery("SELECT * "
5. "FROM Greeting "
6. "ORDER BY date DESC LIMIT 10")
7. for greeting in greetings:
8. if greeting.author:
9. self.response.out.write('%s wrote:' % greeting.author.nickname())
10. else:
11. self.response.out.write
12. self.response.out.write('
13. %s
14. ' %
15. cgi.escape(greeting.content))
编码self.response.out.write("""
3. self.response.out.write(')
4. greetings = db.GqlQuery("SELECT * "
5. "FROM Greeting "
6. "ORDER BY date DESC LIMIT 10")
7. for greeting in greetings:
8. if greeting.author:
9. self.response.out.write('%s wrote:' % greeting.
author.nickname())
10. else:
11. self.response.out.write
12. self.response.out.write('
13. %s
14. ' %
15. cgi.escape(greeting.content))
双引号里使用双引号的方法action设定为url
3. class Guestbook(webapp.RequestHandler):
4. def post(self):
5. greeting = Greeting()
以上内容就是对python语法入门的部分介绍。
1. import cgi
3. import wsgiref.handlers
4. from google.appengine.ext import db
5. from google.appengine.api import users
6. from google.appengine.ext import webapp
创建一个模块,相当于一个数据表,也相当于一个类
1. class Greeting(db.Model):
3. content = db.StringProperty(multiline=True)
4. date = db.DateTimeProperty(auto_now_add=True)
MainPage也是类吧,参数似乎是继承的意思
1. class MainPage(webapp.RequestHandler):
3. self.response.out.write(')
4. greetings = db.GqlQuery("SELECT * "
5. "FROM Greeting "
6. "ORDER BY date DESC LIMIT 10")
