有没有办法用逗号分割字符串只有至少具有特定长度？

Question

我想用逗号分割字符串，但前提是逗号两边的分割长度至少为3个字。

例如，文本："I like playing basketball, football, tennis, which are sports."应转换为：["I like playing basketball, football, tennis", "which are sports."]

Answer 1

尝试用逗号分割字符串然后遍历列表，如果有少于3个字的字符串将它们连接到字符串之前或之后，并从数组中删除它，这样就不会有双精度数。

Answer 2

使用str.split()

例如：

s = ["I like playing basketball, which is a sport." , "Furthermore, I travel a lot."]

result = []
for i in s:
    val = i.split(",")
    if all(len(n.split())>=3 for n in val):   #Check least 3 words 
        result.extend(val)
    else:
        result.append(i)

print(result)

输出：

['I like playing basketball',
 ' which is a sport.',
 'Furthermore, I travel a lot.']

Answer 3

只需使用简单的list理解：

data = ["I like playing basketball, which is a sport.", "Furthermore, I travel a lot."]

result = [sentence.split(',') 
          if all(len(chunk.split()) >= 3 
                 for chunk in sentence.split(',')) 
          else sentence 
          for sentence in data]

print(result)

输出：

[['I like playing basketball', ' which is a sport.'],
 'Furthermore, I travel a lot.']
