如果这是一个list方法,您必须将每个这样的字符串迭代器转换为list,然后才能将元素连接成一个字符串!例如: some_strings = ('foo', 'bar', 'baz') 让我们滚动我们自己的列表连接方法: class OurList(list): def join(self, s): return s.join(self) 要使用它,请注意,我们必须首先从每个可迭代对象中创建...
In English the rules we use for joining a list of items involves more work than a standard join in JavaScript. Here is JavaScript code to join an array of elements with commas (,) and an and. Code /** * Join array of strings with commas (,) and "and". * * @example input ['on...
You can use the join() method to concatenate (join) items in a list to a single string in Python. The join() method takes one argument, which is the list of strings to be joined. Here's an example: words = ['this', 'is', 'a', 'sentence'] sentence = ' '.join(words) ...

The Java 8 has added a new class called StringJoiner to join Strings. The java.util.StringJoiner can be used to join any number of arbitrary String, a list of String, or an array of String in Java. You can choose any delimiter to join String like comma, pipe, colon, or semi-colon....
JavaScript Additionally, you can specify a delimiter as the first argument, which is then added in-between all of the concatenated strings: let string1 = "Java"; let string2 = "Script"; console.log(string1.concat(", ", string2)); This results in: Java, Script Array.prototype.join...
