LIST =["I","am","bigship","come","from","China"]
print (' '.join(LIST))
#2)对字符串进行操作
str="i am bigship"
print('->'.join(str))
#3)对元组进行操作
TUPLE = ("I","am","bigship","come","from","China")
print(' '.join(TUPLE))
#4)对字典进行操作
Dir ={'b':1,'i':2,'g':3,'s':4,'h':5,'p':7}
print( ':'.join(Dir))

I am bigship come from China i-> ->a->m-> ->b->i->g->s->h->i->p I am bigship come from China b:i:g:s:h:p
