[pymvpa] problems with running python scripts in terminal: IndentationError and No output

[Meng Liang]

Dear Yaroslav,
Thanks very much for your quick reply! Now all the problem solved. 
I actually tried "python file.py" way to execute the file before but the terminal was in the python mode (i.e., the terminal has become a python interpreter), so I failed. Once I quit the python in the terminal, python file.py worked! And the output message appears in the terminal window.
Regarding the "Could not save file" problem, I think it is a specific to gedit. I tried the same thing using GVim Text Editor or PsychoPy2 Coder (IDE) and no problem at all.
I am sure I will have more questions to bother you in the future, but as more and more problem solved, I am starting to like the system :-)
Thanks again,Meng
