从字符串列表中删除一个项目

Question

我有一个存储在可变 pdf 路径中的字符串列表，还有另一个字符串列表，如果我的 pdf 路径列表中包含任何项目，则应将其删除。

它适用于某些字符串但不适用于其他字符串，即使该字符串包含相同的词也是如此。

def remove_derivaties(blacklist, pdf_list):
    for x in blacklist:
        for y in pdf_list:
            if x in y:
                pdf_list.remove(y)
    return pdf_list


def main():
    string = ["P:\Example Files\Latest\PRM-FRM-011 Calc Review Form.pdf",
              "P:\Example Files\Latest\PRM-FRM-003 Project Assignment Form.pdf",
              "control_string"]

    exclude = ["P:\Example Files",
               "control_string1"]

    not_excluded = remove_derivaties(exclude, string)
    print(not_excluded)

输出为['P:\Example Files\Latest\PRM-FRM-003 Project Assignment Form.pdf', 'control_string']

然而排除词包含在两个字符串中

Answer 1

这是正确的行为吗？

from typing import List

string = ["P:\Example Files\Latest\PRM-FRM-011 Calc Review Form.pdf",
          "P:\Example Files\Latest\PRM-FRM-003 Project Assignment Form.pdf",
          "control_string"]

exclude = ["P:\Example Files",
           "control_string1"]

def substring_in_string(substring: str, string: str) -> bool:
    return substring in string

def substrings_in_string(substrings: List[str], string: str) -> List[bool]:
    return [substring_in_string(substring, string) for substring in substrings]

not_excluded = [s for s in string if not any(substrings_in_string(exclude, s))]

output:

['control_string']
