Can't see debug print statements using Google App Engine with python <p>I am new to both Google App Engine and Python. When things go wrong I'd like to see variable values and such, but print statements don't seem to be output anywhere. I would have expected them to appear in the same window where I started dev_appserver, but the only time I can see them is if a server error is imminent, then they appear in the output as I'd expect, right before the server error. Otherwise I don't see them.</p> <p>I'm sure I'm missing something very fundamental... it seems everyone else can see their print statements just fine. I have tried using the logger functionality, but best I can tell it is intended for deployed apps. At any rate I can't see any output from those either. A simple example:</p> <pre><code>class PageHandler(BaseHandler): def get(self): // the page renders just fine, but no print statement to be found print "rendering the page!" self.render("page.html") </code></pre> <p>Am I just looking in the wrong spot for the print output? Do I need to be doing something to redirect output before printing? Very confused why the print statements work only when an error is about to occur.</p>
