Python3 如何在 4 个单词后向数组中的每个元素添加 标签？

Question

我有一个数组 ElementA

ElementA=["Hello my name is Karen", "Andrew here with you and nice to meet you", "Hi, Sharon here"]

我希望为数组生成一个输出，它将返回如下:

OutputElementA= ["Hello my name is <br> Karen", "Andrew here with you <br> and nice to meet <br> you", "Hi, Sharon here"]

有人知道如何在每个元素的 4 个单词后将
标记添加到数组中的元素吗？

应该这样做。

ElementA=["Hello my name is Karen", "Andrew here with you and nice to meet you", "Hi, Sharon here"]
OutputElementA = []

for elem in ElementA:
    #Split string into words
    elem_list = elem.split(' ')
    out_elem_str = ''
    i=0
    elem_item = []
    while i < len(elem_list):
        elem_item = elem_list[i:i+4]
        if len(elem_item) == 4:
            out_str = ' '.join(elem_item)+' <br> '
            out_elem_str += out_str
        i+=4
    out_elem_str += ' '.join(elem_item)
    OutputElementA.append(out_elem_str)

print(OutputElementA)

输出是

['Hello my name is <br> Karen', 
'Andrew here with you <br> and nice to meet <br> you', 
'Hi, Sharon here']
