I guess you have two Python versions (2.7 and 3.x), so it could be that 
you've installed smartcard for 3.x and in works in the shell. 
Unfortunately, pySim has not been completely migrated to 3.x yet, so it 
starts under 2.7 by default.  You can try to run it under 3.x:

   python3 ./ -p0

or install the 'smartcard' module for Python 2.7.
