我想将第一次出现的日期或一般的正则表达式带到我的文本的开头:
示例:
"I went out on 1 sep 2012 and it was better than 15 jan 2012"
我想得到
"1 sep 2012, I went out on and it was better than 15 jan 2012"
我正在考虑替换"1 sep 2012",",1 sep 2012,"然后切割字符串,","但我不知道写什么,而不是replace_with:
line = re.sub(r'\d+\s(?:jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\s\d{4}', 'replace_with', line, 1)
任何帮助？
