Create propagation_p368.py #69
Conversation

Dear @fgiovanard, thanks a lot for your first Pull Request! There a a few minor things, which we'll need to fix before merging; see comments. A general remark, please make a few changes to the formatting. I like to stick to pep8 as much as possible. If you want a quick fix, simply use black to reformat it automatically. I think, you could also simply use this online tool for reformatting. Let me know if you need help. |

I forgot to say, please also add a test into the tests subdirectory. (There are plenty of examples about how it's done.) |

Docstrings require a slightly different format (numpy style). See other functions in pycraf as a reference.

In order for the functions in this module to appear in pycraf, it is required to put them into the so-called slots (__all__ = ['findE40', ...] list at the top of the file. See other pycraf modules. Furthermore, in the __init__.py file in the pathprof directory, you need to add from .propagation_p368 import *.

Perhaps it would be cleaner to just have the values for sigma and epsilon (stored as integers) instead of the strings? Could add a comment, what they are.

If you want to make sure that input parameters have a certain value range, you should instead use the @utils.ranged_quantity_input decorator. It also checks the units and applies automatic conversion, if required. It also means that you can work without units in the function core, which may be a bit faster. See other modules, how it's done.

I would probably put the following at the end of the file:
if __name__ == '__main__':
print('This not a standalone python program! Use as module.')
