Python Using Keyword and variable number of arguments in same function

Question

I am wondering if there is a way to do something like this in python 2.7.12

def saveValues(file,*data,delim="|"):

    buf=""

    for d in data:

       buf+=str(d) + delim

    open(file,"w").write(buf[:-1])

So that I have the option to pass delim, or take the default.

Answer 1

It's possible in python3. The python2 workaround is usually this:

def saveValues(file, *data, **kwargs):
    delim = kwargs.pop('delim', '|')
    ...
