如何替换文本中的字符串列表，其中一些字符串是python中其他字符串的子字符串？

def replace_strings(text, strings_to_replace, new_string):
    for string in strings_to_replace:
        start_index = text.find(string)
        while start_index != -1:
            end_index = start_index + len(string)
            text = text[:start_index] + new_string + text[end_index:]
            start_index = text.find(string, start_index + len(new_string))
    return text

# 示例用法
text = "This is a sample text. It contains some sample strings."
strings_to_replace = ["sample", "text"]
new_string = "replacement"
result = replace_strings(text, strings_to_replace, new_string)
print(result)

This is a replacement replacement. It contains some replacement strings.
