Hi Pabitra,
From what I understand, the function total is defined using positional
parameters, while 'name="Adi"' refers to usage of keyword arguments
which is (as I understand) not allowed and this is the cause of the
error. Relevant material which might help in understanding the
underlying mechanisms [0], [1].
The following modification in the code worked for me -
def total(*args, **kwargs):
if args:
print("%s has total money of Rs %d/- " %(kwargs['name'],
sum(args)))
else:
print("%s's piggy bank has no money" %kwargs['name'])
>>> total(*(3000, 10, 45), name="John Doe")
John Doe has total money of Rs 3055/-
Let me know your thoughts. Interesting question btw :)

Hi All,
I want to understand the error message I am getting.
Below is my code piece :-
def total(name, *args):
if args:
print("%s has total money of Rs %d/- " %(name, sum(args)))
else:
print("%s's piggy bank has no money" %name)
I can call this method passing the extra arguments inside *().
I know the correct way of passing the arguments. But, I am passing value
for 'name' in form of param=value, *intentionally*, so that it throws me
error. However, I am unable to understand the below error message :-
>>> total(name="Adi", *(1, 2, 10) )
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: total() got multiple values for keyword argument 'name'
How Python is evaluating the above call, that it's getting multiple values
for the parameter 'name'?
Any help is appreciated.
*Thanks,*
*Pabitra*
