Extract ZipFile using Python, display Progress Percentage?

the extract method doesn't provide a call back for this so one would have to use getinfo to get the e uncompressed size and then open the file read from it in blocks and write it to the place you want the file to go and update the percentage one would also have to restore the mtime if that is wanted an example:

import zipfile
z = zipfile.ZipFile(some_source)
entry_info = z.getinfo(entry_name)
i = z.open(entry_name)
o = open(target_name, 'w')
offset = 0
while True:
    b = i.read(block_size)
    offset += len(b)
    set_percentage(float(offset)/float(entry_info.file_size) * 100.)
    if b == '':
        break
    o.write(b)
i.close()
o.close()
set_attributes_from(entry_info)

this extracts entry_name to target_name

---

most of this is also done by shutil.copyfileobj but it doesn't have a call back for progress either

the source of the ZipFile.extract method calls _extract_member uses:

source = self.open(member, pwd=pwd)
target = file(targetpath, "wb")
shutil.copyfileobj(source, target)
source.close()
target.close()

where member has be converted from a name to a ZipInfo object by getinfo(member) if it wasn't a ZipInfo object

I suggest using tqdm, you can install it using pip like so:

pip install tqdm

Then, you can use it directly like so:

>>> from tqdm import tqdm
>>>
>>> with zipfile.ZipFile(some_source) as zf:
...     for member in tqdm(zf.infolist(), desc='Extracting '):
...         try:
...             zf.extract(member, target_path)
...         except zipfile.error as e:
...             pass

This will produce something like so:

Extracting : 100%|██████████| 60.0k/60.0k [14:56<00:00, 66.9File/s]
