from zipfile import ZipFile
with ZipFile('output.zip', 'w') as z:
z.write('input.txt')
要求:
from os.path import basename
from zipfile import ZipFile
def zip_files(*files):
with ZipFile('output.zip', 'w') as z:
for f in files:
z.write(f, arcname=basename(f))
讲解:
压缩单个目录时, ZipFile 需要 write 目录, 以及目录下每一个文件 (包括子文件夹的文件) 的路径.
这些路径在 zip 文件中有一个公共的前缀, 也就是根目录的目录名, 如下所示:
output.zip
|= root # 这是公共的前缀
|- aaa.txt
|- bbb.txt
|= ccc
|- ddd.txt
import os
import os.path
from zipfile import ZipFile
def zip_dir(dir_):
with ZipFile('output.zip', 'w') as z:
z.write(dir_, arcname=(dn := os.path.basename(dir_)))
for root, dirs, files in os.walk(dir_):
for fn in files:
z.write(
fp := os.path.join(root, fn),
arcname=dn + '/' + os.path.relpath(fp, dir_)
# ^^^^^^^^^^ 特别注意这里.
)
要求:
取它们的公共路径部分作为前缀. 例如:
输入:
c:
|= aaa
|= mmm
|- foo.txt
|= nnn
|- bar.txt
输出:
result.zip
|= mmm
|- foo.txt
|= nnn
|- bar.txt
import os
import os.path
from zipfile import ZipFile
def zip_dirs(*dirs):
prefix = os.path.commonprefix(dirs)
with ZipFile('output.zip', 'w') as z:
for d in dirs:
z.write(d, arcname=os.path.relpath(d, prefix))
for root, dirs, files in os.walk(d):
for fn in files:
z.write(
fp := os.path.join(root, fn),
arcname=os.path.relpath(fp, prefix)
)
我将上述片段合并到一个脚本里面了, 名称为 “ziputil.py”, 代码如下:
import os
import os.path
from zipfile import ZipFile
def zip_file(file_i: str, file_o: str) -> None:
with ZipFile(file_o, 'w') as z:
z.write(file_i, arcname=(n := os.path.basename(file_i)))
print('zip_file:', n)
def zip_files(*files_i: str, file_o: str) -> None:
with ZipFile(file_o, 'w') as z:
for f in files_i:
z.write(f, arcname=(n := os.path.basename(f)))
print('zip_files:', n)
def zip_dir(dir_i: str, file_o: str) -> None:
dir_i_parent = os.path.dirname(dir_i)
with ZipFile(file_o, 'w') as z:
z.write(dir_i, arcname=(n := os.path.basename(dir_i)))
print('zip_dir:', n)
for root, dirs, files in os.walk(dir_i):
for fn in files:
z.write(
fp := os.path.join(root, fn),
arcname=(n := os.path.relpath(fp, dir_i_parent)),
)
print('zip_dir:', n)
def zip_dirs(*dirs_i: str, file_o: str) -> None:
prefix = os.path.commonprefix(dirs_i)
with ZipFile(file_o, 'w') as z:
for d in dirs_i:
z.write(d, arcname=(n := os.path.relpath(d, prefix)))
print('zip_dirs:', n)
for root, dirs, files in os.walk(d):
for fn in files:
z.write(
fp := os.path.join(root, fn),
arcname=(n := os.path.relpath(fp, prefix)),
)
print('zip_dirs:', n)
