How to return a specific value from a function?

Question

Python

Let's say there is a function that returns 3 variables:

def DD():
    aa = "ddcc"
    dd = 2
    cc = 3
    return aa,dd,cc

is it possible to deduce this function so that it would return only the first variable?

Answer 1

def DD():
    aa = "ddcc"
    dd = 2
    cc = 3
    return aa,dd,cc
result, _, _ = DD()

like this

Answer 2

In addition to the fact that you can simply take only the first return value, you can also hang a decorator on the function that will do the same thing
. Something like

def get_first_value(fn):
    def wrapped():
        return fn()[0]
    return wrapped

@get_first_value
def DD():
    aa = "ddcc"
    dd = 2
    cc = 3
    return aa,dd,cc

first_value = DD()

Answer 3

Another option for variety:

>>> def DD():
...     aa = "ddcc"
...     dd = 2
...     cc = 3
...     return aa,dd,cc
...
>>> DD()[0]
'ddcc'

Answer 4

can be unpacked
a, b, c = DD()
