题目：编写一个函数，该函数接受10个整数（0到9之间）的数组，该函数以电话号码的形式返回这些数字的字符串。  

create_phone_number([1, 2, 3, 4, 5, 6, 7, 8, 9, 0]) # => returns "(123) 456-7890"

解答：方案一

def create_phone_number(list):#your code herereturn f"({list[0]}{list[1]}{list[2]})"+" " + f"{list[3]}{list[4]}{list[5]}-{list[6]}{list[7]}{list[8]}{list[9]}" # (123) 456-7890

方案二：

def create_phone_number(n):return "({}{}{}) {}{}{}-{}{}{}{}".format(*n)

Test:

test.describe("Basic tests")test.assert_equals(create_phone_number([1, 2, 3, 4, 5, 6, 7, 8, 9, 0]), "(123) 456-7890")test.assert_equals(create_phone_number([1, 1, 1, 1, 1, 1, 1, 1, 1, 1]), "(111) 111-1111")test.assert_equals(create_phone_number([1, 2, 3, 4, 5, 6, 7, 8, 9, 0]), "(123) 456-7890")test.assert_equals(create_phone_number([0, 2, 3, 0, 5, 6, 0, 8, 9, 0]), "(023) 056-0890")test.assert_equals(create_phone_number([0, 0, 0, 0, 0, 0, 0, 0, 0, 0]), "(000) 000-0000")
