class MainHandler(webapp2.RequestHandler):
def get(self):
    self.response.out.write(form)

def post(self):

Your code example is riddled with TAB characters. If you are mixing tabs with spaces, the error is almost a given.

Use the python tabnanny to clean up your source-code, switch your editor to use spaces only, then fix your indentations:

python -m tabnanny -v path/to/your/code.py

You've mixed up spaces and tabs. Run the script in python -tt to verify.
