Hi PyMOLers,
I am trying to write a python script that will allow a user to provide an
unlimited number of positional arguments for a function. I am use to the
following scheme for defining a function and its arguments:
def some_function ( x, y, z, file="false"):
#DO SOMETHING
return
Where x, y, and z are required arguments and "file=false" is an optional
argument. I came across the following page pertaining to Python:
http://www.linuxtopia.org/online_books/programming_books/python_programming/python_ch15s09.html
See "Unlimited Number of Positional Arguments Values"
There it explains that one could use the following syntax:
def some_function ( *args):
print arg[0]
return
Now, when put this in a script and call the function in PyMOL it spits out the
following error:
Traceback (most recent call last):
File "/pymol/./modules/pymol/parser.py", line 254, in parse
self.result=apply(layer.kw[0],layer.args,layer.kw_args)
TypeError: some_function() got an unexpected keyword argument '_self'
Is the "*args" method simply not possible in PyMOL? I tried using "**args"
which worked nicely for keyword arguments.
Any help would be greatly appreciated. Thank you for your time.
Sean
