Error when using a string as a parameter

Question

I have a list of floats [234, 533, 734, 964, 623, 744, 244, 353, 264]. Then, I format it to a string like "(234, 533, 734), (964, 623, 744), (244, 353, 264)".

This is a format example of the function I'm passing it to:

cmds.curve( p=[(0, 0, 0), (3, 5, 6), (5, 6, 7), (9, 9, 9)] )

Here's what I used that returned an error:

cmds.curve( p = [ pStr ] )

Here's the error:

Line 142: Invalid arguments for flag 'p'. Expected ( distance, distance, distance ), got [ str, str ] #

You must change the string to numbers. Is this a python related question? because you could add Python as a tag too. — Zeddy

Thanks for the quick response Zaf. I have no idea how to do that. Is my approach the correct way? — Warren Daza

There was another question similar here on stack overflow stackoverflow.com/questions/379906/… maybe that help you — Zeddy

Try this and see if it works for you. I have a feeling that you are converting to a string unnecessarily.

floats = [234, 533, 734, 964, 623, 744, 244, 353, 264]
groups = [tuple(floats[i:i+3]) for i in range(0, len(floats), 3] 
cmds.curve(p=groups)

Try using zip, click here for the python docs.

>>> my_list = [234, 533, 734, 964, 623, 744, 244, 353, 264]
>>> zip(*[iter(my_list)]*3)
[(234, 533, 734), (964, 623, 744), (244, 353, 264)]

@askewchan, I used a program called dreampie as my python shell, and it puts those number in there.
