[Tutor] sprintf-like functionality in Python (fwd)

[Danny Yoo]

Hi Vicki,


I'm forwarding this to the Tutor list.  Please be more careful to send
your replies to tutor at python.org next time.

I do not want to become a bottleneck!  Why settle for one brain when you
can use the whole community's?  *grin*



Anyway, for the error you're getting, take a closer look at the original
example.  The original code passes two arguments to the int() function.


Hope this helps!

Thanks. I am closer, and this helps, but I am now getting an error. I am
trying to do:

print "converted " +chr(int(output),16)

and am getting this:
TypeError: chr() takes exactly 1 argument (2 given)

You give two arguments above. What is MY problem?
