Question

This is the error that I get after typing import serial. I’m running osx snow leopard, python3.2 and there were no errors when I installed pyserial.

       import serial
    Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    File "serial/__init__.py", line 21, in <module>
    from serial.serialposix import *
    File "serial/serialposix.py", line 64
    50:      0000001,
               ^

Answer 1

0000001 is an invalid token in Python 3, because it used to be parsed as an octal literal in Python 2, and that behavior was dropped in favor of the 0o prefix.

0o0000001 would work (as would 0o1, or simply 1).

I don’t exactly know why your version of pySerial contains such a literal, but it will not work on Python 3 as it is. Try upgrading, as Martijn suggests.
