类方法
"""# class Juice:

??? Python def function with __init__
❌
MMP 纯属误导呀! --init--
def concatenate(*args):# *args--init--s = ""l = len(list(args))for arg in args:s += (arg + '-')print(concatenate("I", "love", "Python", "!"))
solution
def concatenate(*args):# *argss = ""for arg in args:s += (arg + '-')l = len(s)return s[0:l - 1]# return s.slice(0, l - 1)print(concatenate("I", "love", "Python", "!"))# https://www.sololearn.com/learning/eom-project/1073/358
