最满意答案

最多一次分离到分离器上，并取第一块：

sep = '...' rest = text.split(sep, 1)[0]

你没有说如果分隔符不存在会发生什么。 在这种情况下，这个和Alex的解决方案都将返回整个字符串。

Split on your separator at most once, and take the first piece:

sep = '...' rest = text.split(sep, 1)[0]

You didn't say what should happen if the separator isn't present. Both this and Alex's solution will return the entire string in that case.
