There ate not really any differences in Python itself but there
are some differences in the modules available.

That is what the decimal module is for. I suggest you use it.

Thats because print interprets sequences of bytes as ASCII codes.
The bytes you read from serial are just binary numbers

For currency you need to use the decimal module. Normal floating point
numbers are far too inaccurate for reliable currency conversion.

There are a couple of options. Usually you just want
to display the 2 digit accuracy but keep the real value
as accurate as possible. The easiest way to do that is
to use format strings (as described in

Hi Catherine,
Python does support platform-dependent extensions, and those are used for
things like integrating in

Are there any differences in Python between operating systems or is it really compatible with the majority of operating systems?

To convert character data to integers, you can use the ord()function, and to convert a number to hex notation you can use thehex() function.Example:>>> data ="" "

It is "/usr/bin/env". You could use "/usr/bin/python" instead under
Linux (it might not work under other Unix like OSes).

Hi all,
Is there anyway to set how many numbers are used after the decimal in
floating numbers? It would be nice if the answer could be rounded to 2 decimal
spots, instead of the ten millionths spot.
Thanks in advance,

Hey there,
i am using the serial module and trying to get some info over an RS232
port. Seems to be comming in ok, but when i print it out, its in ASCII
instead of hex. is there a way to have python read serial in hex bytes
instead of ASCII ?
thanks.

I got it working with a utf-8 query by adding an Accept-Charset header to the
request. I used the 'Tamper Data' add-on to Firefox to view all the request
headers being sent by the browser. I added all the same headers to the Python
request and it worked. Then I took out the headers until I found
I'm not exactky sure what's causing the errant behaviour but it might
help if we start off by simplifying the code a little.
