@文心快码python 数组join方法 文心快码 在Python中,join方法是一个非常有用的字符串方法,它可以将一个可迭代对象(如列表、元组等)中的元素连接成一个字符串。下面,我将分点回答你的问题: Python中数组(列表)的概念: Python中没有专门的“数组”类型,但列表(list)是一个常用的数据结构,可以看作是一个可变的...

In Python, joining a list of strings involves concatenating the elements of the list into a single string, using a specified delimiter to separate each element. This operation is particularly useful when you need to convert a list of strings into a single string, such as when you want to sa...
print(list1) Try it Yourself » Or you can use the extend() method, where the purpose is to add elements from one list to another list:Example Use the extend() method to add list2 at the end of list1: list1 = ["a", "b" , "c"]list2 = [1, 2, 3]list1.extend(list2...

str转化为list/tuple,直接进行转换即可。而由list/tuple转换为str,则需要借助join()函数来实现。join()函数是这样描述的: """ S.join(iterable) -> str Return a string which is the concatenation of the strings in the iterable. The separator between elements is S. ...
