import zipfile
from pathlib import Path

with zipfile.ZipFile('/mnt/e/Downloads/hello.zip', 'w') as zfile:
 # zfile.writestr('/path/to/zip/insidefile.txt', "content_str_or_bytes")
 zfile.writestr('folder/age.txt', "12") # 写入 str 类型
 zfile.writestr('raw', "好天气".encode()) # 写入 bytes 类型
 zfile.writestr('demo/qq.exe', Path('/mnt/e/Downloads/qq.exe').read_bytes())

 # 直接写入文件，不需要通过 open 读入内存再写入zip
 zipfile.write("/file/on/disk.txt", "path/in/zipfile/name.txt")

遍历 zip 文件

使用 ZipFile.infolist()

使用 ZipFile.namelist()

In [22]: with zipfile.ZipFile('/mnt/e/Downloads/hello.zip', 'r') as zread:
 ...: print(zread.filelist)
 ...:
[<ZipInfo filename='folder/age.txt' filemode='?rw-------' file_size=2>, <ZipInfo filename='raw' filemode='?rw-------' file_size=9>, <ZipInfo filename='demo/qq.exe' filemode='?rw-------' file_size=183394032>]

使用 ZipFile.filelist 属性

In [24]: with zipfile.ZipFile('/mnt/e/Downloads/hello.zip', 'r') as zread:
 ...: print(zread.namelist())
 ...:
['folder/age.txt', 'raw', 'demo/qq.exe']

使用 zipfile.Path 类 (类似 pathlib.Path)

In [25]: list(zipfile.Path('/mnt/e/Downloads/hello.zip', at='/').iterdir())
Out[25]:
[Path('/mnt/e/Downloads/hello.zip', 'raw'),
 Path('/mnt/e/Downloads/hello.zip', 'folder/'),
 Path('/mnt/e/Downloads/hello.zip', 'demo/')]

 elif isinstance(filename, zipfile.Path):

 for i in iter_path.iterdir():
