Python中的字符串.join()方法是将一个可迭代对象中的字符串元素连接起来,返回一个新的字符串。该方法的语法为:
字符串连接符.join(可迭代对象)
其中,字符串连接符是一个字符串,用于将可迭代对象中的元素连接起来,可迭代对象可以是列表、元组、集合等。
例如,下面的代码将列表中的元素用逗号连接起来:
```
lst = ['apple', 'banana', 'orange']
result = ','.join(lst)
print(result)
```
输出结果为:
```
apple,banana,orange
```

string.join()
The `join()` method is a string method in Python that returns a string concatenated with the elements of an iterable object. The syntax for `join()` is as follows:
`string.join(iterable)`
Here, `string` is the string that will be used as a separator between the elements of the iterable, and `iterable` is the iterable object that contains the elements to be joined. The iterable can be a list, tuple, or any other sequence.
For example, let's say we have a list of strings:
```
my_list = ['Hello', 'world', 'how', 'are', 'you']
```
We can use the `join()` method to concatenate the elements of the list with a space separator:
```
my_string = ' '.join(my_list)
```
The resulting string would be:
```
'Hello world how are you'
```
Note that the separator (in this case, a space) is placed between each element of the iterable, except for the last element.
