实例讲解join方法的使用

str.join(sequence)

sequence   要连接的元素序列、字符串、元组、字典

返回通过指定字符连接序列中的元素后生成的新的字符串

str = "-";

seq = ("a", "b", "c")  #字符串序列

print str.join(seq)

a-b-c

#1)对序列进行操作

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

list = ['a','b','c','d']

print('+'.join(list))

输出结果为：

a+b+c+d
