Is there syntax that allows you to expand a list into the arguments of a function call?
Example:
# Trivial example function, not meant to do anything useful.
def foo(x,y,z):
return "%d, %d, %d" %(x,y,z)
# List of values that I want to pass into foo.
values = [1,2,3]
# I want to do something like this, and get the result "1, 2, 3":
foo( values.howDoYouExpandMe() )
You should use the * operator, like foo(*values)
Read the Python doc unpackaging argument lists.
Also, do read this: http://www.saltycrane.com/blog/2008/01/how-to-use-args-and-kwargs-in-python/
def foo(x,y,z):
return "%d, %d, %d" % (x,y,z)
values = [1,2,3]
# the solution.
foo(*values)
That can be done with:
foo(*values)
