Google App Engine httplib2 import Http results in Syntax Error

Looking for some help with Google App Engine. Below is the offending part of my code:

from __future__ import print_function
import webapp2
import jinja2
import csv
import os
from collections import namedtuple
from httplib2 import Http
from googleapiclient.discovery import build
from oauth2client import file, client, tools
import datetime
##code to do stuff

Where I'm running into trouble is with the "from httplib2 import Http" line. I'm getting the following error:

Traceback (most recent call last):
  File "/base/alloc/tmpfs/dynamic_runtimes/python27g/c3b7fd7c606f3aa7/python27/python27_lib/versions/1/google/appengine/runtime/wsgi.py", line 240, in Handle

    print('%s:' % h, end=' ', file=self._fp)
                        ^
SyntaxError: invalid syntax

I've got the httplib2 module files in my app directory. I've been googling around but nobody seems to have had this issue - can someone help?

THANK YOU!

Solution

Please read about MCVEs. It would appear that the MCVE for this issue is one line:

from httplib2 import Http

I believe your issue is that your httplib2 module lacks the needed future import.

from __future__ import print_function

Future imports only apply to the module in which they appear. Without it, in 2.7, one gets the traceback you got.

>>> print(1, 2, end='')
  File "<stdin>", line 1
    print(1, 2, end='')
                   ^
