我想使用python将这些数据整形为以下格式。

我想在冒号之后移动文本，但我不知道如何。

Answer 1

import re

text = '''your_text_here'''

text = re.sub("Review Content :\s+", "Review Content : ", text)
text = re.sub("Review Title : ", "\n\nReview Title : ", text)
text = text.strip()

print(text)

使用re library可以更轻松地对字符串进行操作：

第一个sub替换了＆＃34;回顾内容＆＃34;之后的空白字符链。只有1个空间。多亏了你的内容和＃34;评论内容＆＃34;标签
第二个sub在＆＃34;评论标题＆＃34;之前添加了2个换行符。标签
strip()从字符串的开头和结尾删除空格，这有效地删除了在第一个＆＃34; Review Title＆＃34;之前添加的两个换行符。在上一步中
