推荐答案

在分隔符上最多拆分一次，并取第一块:

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

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

您没有说明如果分隔符不存在会发生什么.在这种情况下，this 和 Alex 的解决方案都将返回整个字符串.

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.
