For simple strings I use the "%s" % foo version, for more complex stuff I use
the .format() method. I find it easier to control spacing and alignments with
the .format() method, but that's just me.

Use locale.format():

In [2]: f=1222333.4
In [6]: locale.setlocale(locale.LC_ALL, "")
Out[6]: 'English_United States.125

Why is it that this prints as

And this doesn't?
channel, info = server.accept()
