Hello, As someone just learning Python from Bash/C++ background, I would like to suggest a small addition to 2.1.2: how to execute a script inside the shell (similar to bash 'scriptname', 'source script' or '. script'): import fn, or reload(fn) related, it would be nice to have info near the beginning of the tutorial how to call system commands: import os; os.system('..') --thanks, Chris Christopher Crawford Dept. of Physics & Astronomy University of Kentucky 373 C.-P.
