Python正则表达式函数

我想删除python列表中第一个条目前所有不必要的粗体字符。我正在尝试使用正则表达式来实现它，请检查我的代码

编辑：我想删除单词safe之前的所有字符

OP：粗体文本没有规则。假设损坏的文本将以安全结尾：

输出：

粗体文本的规则是什么？请参阅以获取实际示例。return re.subr'^.*？a01'，r'\1'，text？如果所有垃圾字符都出现在字符串的开头，而实际数据以a01开头，那么这将起作用。您的问题是。*是贪婪的，如果您使用。*使其非贪婪，它将匹配所有内容，直到最后出现a01为止？在1月的演示中，应该可以使用粗体文本，但没有规则。我只想删除那些不必要的字符。生成的代码是什么样子的？如果没有需求，就无法解决编程任务。如果你没有这方面的规定，就按原样离开，总比进一步腐蚀好。
