需要在上面的代碼中調(diào)整以下兩個變量

days = 30 path = '/PATH_TO_DELETE'

按大小刪除文件

調(diào)整以下兩個變量。

path = 'ENTER_PATH_HERE' size = 500

按擴展名刪除文件

在某些情況下，您想按文件的擴展名類型刪除文件。假設(shè).log文件。我們可以使用該os.path.splitext(path)方法找到文件的擴展名。它返回一個元組，其中包含文件的路徑和擴展名。

# importing os moduleimport os# main functiondef main(): # specify the path path = 'PATH_TO_LOOK_FOR' # specify the extension extension = '.log' # checking whether the path exist or not if os.path.exists(path):# check whether the path is directory or not if os.path.isdir(path): # iterating through the subfolders for root_folder, folders, files in os.walk(path):# checking of the filesfor file in files: # file path file_path = os.path.join(root_folder, file) # extracting the extension from the filename file_extension = os.path.splitext(file_path)[1] # checking the file_extension if extension == file_extension:# deleting the file if not os.remove(file_path): # success message print(f'{file_path} deleted successfully') else: # failure message print(f'Unable to delete the {file_path}')else: # path is not a directory print(f'{path} is not a directory') else:# path doen’t exist print(f'{path} doesn’t exist')if __name__ == ’__main__’: # invoking main function main()

不要忘記更新上面代碼中的path和extension變量，以滿足您的要求。
