需要在上面的代碼中調(diào)整以下兩個(gè)變量

days = 30 path = '/PATH_TO_DELETE'

按大小刪除文件

# importing the os moduleimport os# function that returns size of a filedef get_file_size(path):# getting file size in bytessize = os.path.getsize(path)# returning the size of the filereturn size# function to delete a filedef remove_file(path):# deleting the fileif not os.remove(path):# successprint(f'{path} is deleted successfully')else:# errorprint(f'Unable to delete the {path}')def main():# specify the pathpath = 'ENTER_PATH_HERE'# put max size of file in MBssize = 500# checking whether the path exists or notif os.path.exists(path):# converting size to bytessize = size * 1024 * 1024# traversing through the subfoldersfor root_folder, folders, files in os.walk(path):# iterating over the files listfor file in files:# getting file pathfile_path = os.path.join(root_folder, file)# checking the file sizeif get_file_size(file_path) >= size:# invoking the remove_file functionremove_file(file_path)else:# checking only if the path is fileif os.path.isfile(path):# path is not a dir# checking the file directlyif get_file_size(path) >= size:# invoking the remove_file functionremove_file(path)else:# path doesn’t existprint(f'{path} doesn’t exist')if __name__ == ’__main__’:main()

調(diào)整以下兩個(gè)變量。

path = 'ENTER_PATH_HERE' size = 500

按擴(kuò)展名刪除文件

在某些情況下，您想按文件的擴(kuò)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(kuò)展名。它返回一個(gè)元組，其中包含文件的路徑和擴(kuò)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。
