如何将元组作为参数并返回由参数的前三个和后三个元素组成的元组

Question

In a function, I need to return a tuple consisting the first 3 and last 3 elements of the argument. I have tried the min and max but i need to get (10,20,30,70,80,90)

so for example:

if the function is called with the tuple (0,10,20,30,40,50,60,70,80,90) as argument, the function supposed to return (10,20,30,70,80,90). Can someone please explain to me or give me a hint on what should I do?

this is my current code:

def first3_last3(t):
    return min(t), max(t)


t = (10,20,30,40,50,60,70,80,90)
print(first3_last3(t))

Answer 1

You can also use the splat operator * to merge the sliced tuples:

def first3_last3(t):
    return (*t[:3], *t[-3:])

t = (10,20,30,40,50,60,70,80,90)
print(first3_last3(t))

Output:

>> (10, 20, 30, 70, 80, 90)

Answer 2

Sorting (if it's unsorted) and using slicing gives you the output you are looking for.

def first3_last3(t):
    t = sorted(t)
    return tuple(t[:3] + t[-3:])


t = (10,20,30,40,50,60,70,80,90)
print(first3_last3(t))

returns

(10, 20, 30, 70, 80, 90)
