Hi,
I'm trying to write a function that will either take arguments when the
function is called, such as myFunc(x,y,z) or if the user does not enter
any arguments, myFunc() the raw_input function will ask for them. But I
dont know how to check how many arguments have been entered. My code is
below. Anyone know how??
Does this suit your requirements?
def myFunc(x=None, y=None, z=None):
if x is None:
x = float( raw_input("Please enter a value for x: ") )
if y is None:
y = float( raw_input("Please enter a value for y: ") )
if z is None:
z = float( raw_input("Please enter a value for z: ") )
# do something with x, y, z
I've assumed that you want float arguments. If not, change the calls to float
to something else, or to leave them as strings, remove them altogether.
