如何返回字符串第二次出现后的所有内容

def get_after_second_occurrence(string, target):
    first_occurrence = string.find(target)
    if first_occurrence != -1:
        first_occurrence += len(target)
        second_occurrence = string.find(target, first_occurrence)
        if second_occurrence != -1:
            return string[second_occurrence + len(target):]
    return ""

# 示例用法
text = "This is a sample text. This is the second occurrence. This is the third occurrence."
result = get_after_second_occurrence(text, "This")
print(result)
