Basically, it flattens the list the splat is before (or in this case, a variable that dereferences to a list).
Here's an rip of one of the examples at said source as I'm too lazy to write out my own right now.
Without me retyping, here's an answer on stackoverflow.Originally Posted by Thereoncewasamaninparis
Code:
The (*c) syntax is what is throwing me off, it's looks very much like a ptr, but obviously isn't.Code:#!/usr/bin/python colors = ["red","blue","green","yellow","brown","black"] months = ( "Jan","Feb","Mar","Apr","May","Jun", "Jul","Aug","Sep","Oct","Nov","Dec", ) for c in enumerate(colors): print "{0} {1}".format(*c) print for num,month in enumerate( months, 1 ): print "{0} {1}".format( num, month )
I assume it's use is for the {0} and the {1} since only one variable is provided, I just can't find anything on google, any idea what the name is of that * operator? Even when I find a list of python images, I don't get * for multiplication, *= assignment and ** for exponents.

Code:
>>> def foo(a, b=None, c=None):
... print a, b, c
...
>>> foo([1, 2, 3])
[1, 2, 3] None None
>>> foo(*[1, 2, 3])
1 2 3
>>> def bar(*a):
... print a
...
>>> bar([1, 2, 3])
([1, 2, 3],)
>>> bar(*[1, 2, 3])
(1, 2, 3)
