我想把文字移到冒号后面，但我不知道怎么做。你知道吗

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将“Review Content”后面的空白字符链替换为1个空格。感谢你有内容在同一行作为“审查内容”标签
• 第二个sub在“Review Title”标签前添加2个换行符
• strip()删除字符串开头和结尾的空白，这有效地删除了前一步中第一个“审阅标题”前面添加的两个换行符
