我们来看 官网api解释: Java代码 /** The limit parameter controls the number of times the pattern is applied and therefore affects the length of the resulting array. If the limit n is greater than zero then the pattern will be applied at most n - 1 times, the array's length will be no...

If a limit is specified, the returned array will not be longer than the limit. The last element of the array will contain the remainder of the string, which may still have separators in it if the limit was reached.Tip: See the Java RegEx tutorial to learn about regular expressions....

The string whose method is called is inserted in between each given string. The result is returned as a new string. Example: '.'.join(['ab', 'pq', 'rs']) -> 'ab.pq.rs' """pass 看了构造就知道函数内需要传入可迭代对象,所以我们先传入一个列表演示一下。
