Convert variable directly into a string (no ASCII)

[Justin Rajewski]

Hello,

I need to print variables out over serial, however I need them to not be
in ASCII, ie if the variable is 5 then print 5 not "5".

The function that writes to the serial port requires a string and I can
send non-variables out with the string "/x05" for 5.

Is this even possible?

Thanks,
Justin

See module struct:
'\x05\x96\x03\xe0'

So you have a number N given, between 0 and 255, and you want to send
the byte whose ordinal is N. Right? Send chr(N).

Take a look at the chr() function. For completeness, the complementary one
is ord(). However, also take a look at the 'struct' module, which is the
tool of choice if you want to do other formatting operations.

I seem to remember there was a third tool that can be used for similar
tasks, but I forgot which it was...
