Python3将ipa包中的文件按大小排序

[本文出自天外归云的博客园]

给你个ipa包，解压前输出包大小，解压后把里面的文件按大小排序。代码如下：

import os
import shutil
import zipfile

_ipa_zip_path = lambda ipa_path: ipa_path.replace('.ipa', '.zip')
_file_size = lambda file_path: os.path.getsize(file_path) / 1024 / 1024

def unzip(zip_path: str) -> str:
    dir_path = None
    if zip_path.endswith('.zip'):
        print(f'{zip_path} file size:{round(_file_size(zip_path),3)}mb')
        zip_name = os.path.basename(zip_path)
        dir_name = zip_name.replace('.zip', '')
        dir_root_path = zip_path.replace(zip_name, '')
        dir_path = os.path.join(dir_root_path, dir_name)
        if os.path.exists(dir_path):
            shutil.rmtree(dir_path)
        os.mkdir(dir_path)
        zip_file = zipfile.ZipFile(zip_path)
        for file_name in zip_file.namelist():
            zip_file.extract(file_name, dir_path)
        zip_file.close()
    return dir_path

def rename_suffix(raw, raw_type, target) -> None:
    if raw.endswith(raw_type) and os.path.exists(raw):
        os.rename(raw, target)

def walk_files(dir_path) -> list:
    file_dicts = []
    if os.path.exists(dir_path):
        for root, dirs, files in os.walk(dir_path, topdown=True):
            for name in files:
                file_path = os.path.join(root, name)
                file_dict = {
                    'file_name': name,
                    'file_size': round(_file_size(file_path), 8),
                }
                file_dicts.append(file_dict)
    return file_dicts

def show_files_size(dir_path=None) -> None:
    if dir_path:
        file_dicts_sorted = sorted(walk_files(dir_path),
                                   key=lambda e: (e.__getitem__('file_size'), e.__getitem__('file_name')), reverse=True)
        for file_dict in file_dicts_sorted:
            print(f'{file_dict["file_name"]}->{file_dict["file_size"]}mb')

def ipa_checker(ipa_path: str) -> None:
    try:
        ipa_file_size = _file_size(ipa_path)
        print(f'{ipa_path} file size:{round(ipa_file_size,3)}mb')
    except FileNotFoundError as error:
        print(f'File not exists->{ipa_path}')
    ipa_zip_path = _ipa_zip_path(ipa_path)
    rename_suffix(ipa_path, '.ipa', ipa_zip_path)
    try:
        dir_path = unzip(ipa_zip_path)
        show_files_size(dir_path)
    except OSError as error:
        print(error)

if __name__ == '__main__':
    ipa_path = r'C:\Users\kkk\Desktop\xxx.ipa'
    ipa_checker(ipa_path)

哦了。
