Iterating through a tuple using a function and *args

Question

I'm trying to make a function using *args. It should take in certain numbers and then output the products of the numbers multiplied by 10.

I'm learning to use *args but I'm having trouble getting the output. My result only outputs the first number in the function. I've tried using a for loop, thinking it would iterate over each character, but it didn't work.

def myfunc(*args):
for args1 in args:
    return args1*10

When I run the function:

myfunc(10.1,20)

The expected output should be

(101.0,200.0)

The actual output is

(101.0)

Any help would be appreciated. Thanks.

If I understand you, that's what you need:

def myfunc(*args): 
    return tuple(map(lambda x: x*10, args))

*args can be retrieved in the function as a list called args. What you do here is just multiplying the first element by 10 and return it, so the function stops.

You should use yield instead of return, to make your function return a generator, which can then be converted to tuple whenever you need

>>> def myfunc(*args):
...     for args1 in args:
...         yield args1*10
... 
>>> 
>>> myfunc(10.1,20)
<generator object myfunc at 0x7f20d1ae8ad0>
>>> 
>>> tuple(myfunc(10.1,20))
(101.0, 200)
