Remember that when you execute the code via "C-c C-c" it is run in a
temporary file which is not in the same folder as the org file from where
it was generated from. Maybe you are reading some data from a file and
Python is not able to locate the file when run with "C-c C-c".

Put ":results output" in the header and then print the current working
directory to see what I mean. If this is the problem, use the full path to
load any data you need in the python code. Remember you can use variables
in org-babel to pass this path to python, such as ":var
datapath="some_path_or_lisp_function_to_get_the_path" in the babel header..
