The previous approach executed the entered script line-by-line, it was not possible to execute multi-line statements, for example: for i in range(0, 10): print(i) because PyRun_SimpleString was complaining about the colon. To avoid all these extra steps we can concatenate all the lines into one, and then execute it, instead of creating a temporary file. This will delegate error handling to Python.
