我正在嘗試提取 C:/Folder 下的頂級目錄列表。然后我想檢查每個目錄的修改日期。我可以用next(os.walk(source_dir))[1] 獲取目錄列表。但是當我嘗試使用os.stat(str(dir_list))[stat.ST_MTIME]要獲取每個目錄的修改日期，它似乎將所有目錄名稱作為一個大名稱進行搜索。這給了我一個 File Not Found 錯誤。如何獲取每個子目錄的修改日期而不會出現 File Not Found 錯誤？import os.pathimport time, stat# Source directorysource_dir = r'C:/Folder'def check_dir(): if not os.path.isdir(source_dir): # Needed to detect top level files print("Nothing in top folder.") else: dir_list = next(os.walk(source_dir))[1] print(dir_list) # get modified time for directories dtime = os.stat(str(dir_list))[stat.ST_MTIME] if time.time() - dtime <= 7776000: print("Found modification in last 90 days for folder =>", dir_list, time.ctime(dtime))if __name__ == "__main__": check_dir()

您不能os.stat用于必須遍歷列表的列表：
def check_dir():
if not os.path.isdir(source_dir):
# Needed to detect top level files
print("Nothing in top folder.")
else:
root, dir_list, _ = next(os.walk(source_dir))
print(dir_list)
# get modified time for directories
for dir in dir_list:
dtime = os.stat(str(root + os.path.sep + dir))[stat.ST_MTIME]
if time.time() - dtime <= 7776000:
print("Found modification in last 90 days for folder =>", dir, time.ctime(dtime))
if __name__ == "__main__":
check_dir()

問題是它os.walk為您提供了一個相對路徑，source_dir例如：
import os
source_dir = '/tmp/'
relative_paths = [relative_path for relative_path in next(os.walk(source_dir))[1]]
print(relative_paths)
>>> ['com.google.Keystone', 'com.apple.launchd.liNmfkel1M', 'powerlog']
為了獲取統計信息，您需要使用每個文件夾的完整路徑，例如：
import os
import stat
source_dir = '/tmp/'
full_paths = [os.path.join(source_dir, relative_path) for relative_path in next(os.walk(source_dir))[1]]
print(full_paths)
>>> ['/tmp/com.google.Keystone', '/tmp/com.apple.launchd.liNmfkel1M', '/tmp/powerlog']
然后你可以使用它們：
import os
import stat
source_dir = '/tmp/'
full_paths = [os.path.join(source_dir, relative_path) for relative_path in next(os.walk(source_dir))[1]]
stats = [os.stat(path)[stat.ST_MTIME] for path in full_paths]
print(stats)
>>> [1581523169, 1581523164, 1581523141]
