Carey McGarvey Jr. shares his Maya Curve Converter Script which provides a handy interface for converting MEL curves in Maya to Python while storing the curve code so you can return to Curve Converter tool and re-create the stored curves you have. Check out the Maya Curve Converter script here.
Carey McGarvey Jr. writes on his Maya tool: I originally started this small project to make a quick converter for getting MEL curves to Python. I quick realized that a nice little interface that stored the generated code for later use would be better then making shelf buttons for each and every curve you wanted to keep for later use. The tool, upon conversion will give you the option the grab the code and just use it as is, or give it a name and store it. The tool will store the converted commands inside a .txt in the same location as where the script is being loaded from. This tool will also give you the option to select a stored curve and have the command printed out into the script editor in-case you want to pass it on to someone else.
