The 2 lines after the sleep(0.5) both times look to be incorrectly indented. The first line (beginning content, response_code= is indented at the level of the if statement so you have left that if block, then the next line is else: which is indented even further than any matching if. Python requires correct indentation.

Looks to me you're mixing tabs and spaces. That will cause problems in Python...
This is how it looks like in my editor

The 'now' line has a single tab and the 'if' line has 8 spaces.
