22.用于压缩文件夹和文件的Python脚本

import zipfile
import sys
import os# 压缩文件功能
def zip_file(file_path):compress_file = zipfile.ZipFile(file_path + '.zip', 'w')compress_file.write(path, compress_type=zipfile.ZIP_DEFLATED)compress_file.close()# 声明函数以返回特定目录的所有文件路径
def retrieve_file_paths(dir_name):# 设置文件路径变量file_paths = []# 读取所有目录、子目录和文件列表for root, directories, files in os.walk(dir_name):for filename in files:# 使用os模块创建完整的文件路径。file_path = os.path.join(root, filename)file_paths.append(file_path)# 返回所有路径return file_pathsdef zip_dir(dir_path, file_paths):# 将文件和文件夹写入zip文件compress_dir = zipfile.ZipFile(dir_path + '.zip', 'w')with compress_dir:# 分别写入每个文件for file in file_paths:compress_dir.write(file)if __name__ == "__main__":path = sys.argv[1]if os.path.isdir(path):files_path = retrieve_file_paths(path)# 打印要压缩的文件列表print('The following list of files will be zipped:')for file_name in files_path:print(file_name)zip_dir(path, files_path)elif os.path.isfile(path):print('The %s will be zipped:' % path)zip_file(path)else:print('a special file(socket,FIFO,device file), please input file or dir')

23.文字转语音

from gtts import gTTS 
import os
file = open("abc.txt", "r").read()speech = gTTS(text=file, lang='en', slow=False)
speech.save("voice.mp3")
os.system("voice.mp3")
