将字符串每n个单词拆分为较小的字符串

Question

情况: 我有一大段文本，想要将其拆分成更小的字符串。每n个单词为一个字符串。

text = "This is a small example Text, showcasing my desired output."

应该使用n = 4进行拆分：

textList = ['This is a small', 'example Text, showcasing my', 'desired output.']    

我的想法是使用以下方式将其拆分为仅包含单词的列表：

n = len(text)    
textList = text.split(' ', n)   

然后使用join()将其组合在一起，但我卡住了，因为：

for x in range(0, 3):
    ' '.join(textList)

没有将列表组合成我想要的输出

尝试使用re.findall(r'\W*(?:\w+\W+){1,4}', text)。 - Wiktor Stribiżew

Answer 1

试试这个：

text = 'This is a small example Text, showcasing my desired output.'
text = text.split()
n = 4
[' '.join(text[i:i+n]) for i in range(0,len(text),n)]

Answer 2

text = "This is a small example Text, showcasing my desired output."

def split_sentence(texto):
    split_texto = texto.split()
    comb_st = [] # Combinaciones split
    i = 0
    for st in split_texto:
        comb_st.append(st)
        if split_texto == split_texto[-1]:
            break
        else:
            add_st = ""
            for cs2 in split_texto[i + 1: ]:
                add_st += " " + cs2
                add_st = add_st.lstrip()
                comb_st.append(st + " " + add_st)
        i += 1
    # for i in range(len(comb_st)):
    #     comb_st[i] = comb_st[i].split()
    return comb_st

comb_split_texto = split_sentence(text)
