在这段代码中，我得到了一个存在于基本路径中的路径，它正确地获取了路径，但问题是我想将该函数保存在另一个名为 hi 的变量中，但每当我打印它时，它给了我结果None

import os
def contain(dirname, dPath):
    dirfiles = os.listdir(dirname)

    fullpaths = map(lambda name: os.path.join(dirname, name), dirfiles)
    dirs = []

    for file in fullpaths:
        if os.path.isdir(file): dirs.append(file)

    folder = list(dirs)
    watching = [s for s in folder if dPath in s]
    copy = str(watching)[2:-2]
    print(copy)

def hello():
    base = '/home/bilal/Videos/folder1'
    destination = '/home/bilal/Videos/folder1/fd'
    hi = contain(base, destination)
    print(f"This is another time: {hi}")
    
hello()

应该是这样的：

import os
def contain(dirname, dPath):
    dirfiles = os.listdir(dirname)

    fullpaths = map(lambda name: os.path.join(dirname, name), dirfiles)
    dirs = []

    for file in fullpaths:
        if os.path.isdir(file): dirs.append(file)

    folder = list(dirs)
    watching = [s for s in folder if dPath in s]
    copy = str(watching)[2:-2]
    return copy#you need to return a value


def hello():
    base = '/home/bilal/Videos/folder1'
    destination = '/home/bilal/Videos/folder1/fd'
    hi = contain(base, destination)
    print(f"This is another time: {hi}")
    
hello()
