This article introduces the relevant knowledge of "what are the compression and decompression methods of Python files?" in the operation of actual cases, many people will encounter such a dilemma, and then let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Foreword:

Python has been widely used in artificial intelligence, background service and other fields. Because python has a large number of third-party open source packages and its easy-to-use language features, this language has strong advantages in data processing, batch processing and other methods, and is quite convenient to use.

Installation:

Pip install zipfile

Code:

1. Compress the entire folder import zipfileimport osfrom tqdm import tqdmdef zip_file (src_dir) Save_name='default'):''all files and folders under the compressed folder default compressed file name: folder name default compressed file path: folder upper directory''if save_name= = 'default': zip_name = src_dir +' .zip 'else: if save_name is None or save_name= ='': Zip_name = src_dir + '.zip' else: zip_name = save_name + '.zip' z = zipfile.ZipFile (zip_name For dirpath, dirnames, filenames in os.walk (src_dir): fpath = dirpath.replace (src_dir,'') fpath = fpath and fpath + os.sep or''for filename in filenames: z.write (os.path.join (dirpath, filename), fpath + filename) z.close () return True2, compression specified extension file def zip_file_by_extension (src_dir) Extension='dll', save_name='default'):''filter the files to be compressed according to the file extension Note: for single-tier directories The subfiles under the folder will not be compressed''if save_name = = 'default': zip_name = src_dir +' .zip 'else: if save_name is None or save_name = =': zip_name = src_dir + '.zip' else: zip_name = save_name + '.zip' z = zipfile.ZipFile (zip_name,'w') Zipfile.ZIP_DEFLATED) file_list = os.listdir (src_dir) for filename in tqdm (file_list): if not os.path.isfile (os.path.join (src_dir, filename)): continue if filename.split ('.)
