Python keyword-only parameters: Setting default values

Keyword-only parameters in a Python function can have a default:

def myfunc(*, a, b=10):
    return f'{a=}, {b=}'

Now call it:

myfunc(a=5)        # use the default
myfunc(a=5, b=6)   # override the default

Remember: parameters with defaults come *after* those without.
