Any answers would be accepted.
Thank you!pizzaSat, 18 Aug 2018 01:26:01 -0500http://ask.sagemath.org/question/43409/Syntax differences with pythonhttp://ask.sagemath.org/question/38777/syntax-differences-with-python/Hello,
I'm trying to do a tricky function that requires a unknown number or regular argument, some default keywords argument and any number of other keyword argument.
In python, this code works:
def addplot_coordinates(*args, plus_option=False, **kwargs):
pass
But it doesn't work with sage:
sage: def addplot_coordinates(*args, plus_option=False, **kwargs):
....: pass
File "<ipython-input-1-dace1b5103c9>", line 1
def addplot_coordinates(*args, plus_option=False, **kwargs):
^
SyntaxError: invalid syntax
I naively though that any correct python code would work with sage. I found here* that there is some «minimal syntax difference», and searching «sage python syntax difference» on a search engine does not give relevant results.
Is there a document listing all the things someone coming from python should be careful about ? Can someone give me a pointer to such a document ?
Thank you for your time.

in sage so that sage can differ between symbolic $$y_{k+1}$$ and $$y_{k}$$.
Would somebody please help?
