??? 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", "!"))

def concatenate(*args):
# *args
s = ""
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", "!"))
