Keyword arguments are going to be the best solution, but you'll still
have to do checks like in this example which uses a generic keyword
and determines it's type..
def getBook(arg):
id = None
name = None
try:
id = int(arg)
# use the id here
except ValueError:
name = arg
# use name here
Now, if you were to use named arguments:
def getBook(id=None, name=None):
if id:
# do whatever for id
elif name:
# do whatever for name here
They are nearly identical.
