I often use library functions which return many values in a tuple:
def f():
return "a", "b", "c", "d"
Is it possible to (in a single step) unpack the first value while keeping the rest in a tuple? Ie do this:
ret = f()
a, b_to_d = ret[0], ret[1:]
but in one line.
Yes, using the *
syntax below:
>>> def f():
... return 1,2,3,4
...
>>> a,*b = f()
>>> a
1
>>> b
[2, 3, 4]
>>> a,*b,c = f() # * can be used in other positions, too
>>> a,b,c
(1, [2, 3], 4)
