1. Распакивање зип датотеке

# importing required modules from zipfile import ZipFile # specifying the zip file name file_name = 'my_python_files.zip' # opening the zip file in READ mode with ZipFile(file_name 'r') as zip: # printing all the contents of the zip file zip.printdir() # extracting all the files print('Extracting all the files now...') zip.extractall() print('Done!') 

• from zipfile import ZipFile

  ZipFile is a class of zipfile module for reading and writing zip files. Here we import only class ZipFile from zipfile module.

• with ZipFile(file_name 'r') as zip:

  Here a ZipFile object is made by calling ZipFile constructor which accepts zip file name and mode parameters. We create a ZipFile object in ПРОЧИТАЈТЕ режим и назовите га као зип .

• zip.printdir()

  принтдир() метода штампа садржај за архиву.

• zip.extractall()

  екстракталл() метод ће издвојити сав садржај зип датотеке у тренутни радни директоријум. Можете и позвати екстракт() method to extract any file by specifying its path in the zip file. For example:

  zip.extract('python_files/python_wiki.txt')

  This will extract only the specified file. If you want to read some specific file you can go like this:

  data = zip.read(name_of_file_to_read)

2. Писање у зип датотеку

# importing required modules from zipfile import ZipFile import os def get_all_file_paths(directory): # initializing empty file paths list file_paths = [] # crawling through directory and subdirectories for root directories files in os.walk(directory): for filename in files: # join the two strings in order to form the full filepath. filepath = os.path.join(root filename) file_paths.append(filepath) # returning all file paths return file_paths def main(): # path to folder which needs to be zipped directory = './python_files' # calling function to get all file paths in the directory file_paths = get_all_file_paths(directory) # printing the list of all files to be zipped print('Following files will be zipped:') for file_name in file_paths: print(file_name) # writing files to a zipfile with ZipFile('my_python_files.zip''w') as zip: # writing each file one by one for file in file_paths: zip.write(file) print('All files zipped successfully!') if __name__ == '__main__': main() 

• def get_all_file_paths(directory): file_paths = [] for root directories files in os.walk(directory): for filename in files: filepath = os.path.join(root filename) file_paths.append(filepath) return file_paths

  First of all to get all file paths in our directory we have created this function which uses the ос.валк()  методом. У свакој итерацији све датотеке присутне у том директоријуму се додају листи која се зове филе_патхс . На крају враћамо све путање датотека.

• file_paths = get_all_file_paths(directory)

  Here we pass the directory to be zipped to the гет_алл_филе_патхс() функцију и добијање листе која садржи све путање датотека.

• with ZipFile('my_python_files.zip''w') as zip:

  Here we create a ZipFile object in WRITE mode this time.

• for file in file_paths: zip.write(file)

  Here we write all the files to the zip file one by one using писати методом.
