Question

form="""
<textarea>%s</textarea>
"""

I am trying to make a post request using the textarea input, and show the post input in the textarea again and I am able to do that.

But, my problem is in the beginning when I first go to see the page, I see the %s in the textarea box. How do I hide the %s? I am using the old python, I think it is 2.7

form="""
    <form method="post">
      <textarea name="text">%s</textarea>
  <br>
  <input type="submit">
</form>
"""        
class MainPage(webapp2.RequestHandler):
  def get(self):
      self.response.write(form)
  def post(self):
      foo="posted to the box"
      self.response.write(form %foo)
app = webapp2.WSGIApplication([('/', MainPage)], debug=True)

Answer 1

Try following code

print form.replace('%s', '')
