将字符串转换为路径以在 Google Colaboratory 中与 Unzip 一起使用

Question

I'm working with a Jupyter notebook in Google Colaboratory and I want to unzip file that it is on my Google Drive into /tmp folder.

I have tried this:

import os

root_dir = '/tmp/omniglot/data/'
!unzip '/content/gdrive/My Drive/Colab Notebooks/data/omniglot.zip' -d path.path(root_dir)

But I get the error:

syntax error near unexpected token `('

I have also tried:

from pathlib import Path

root_dir = '/tmp/omniglot/data/'
!unzip '/content/gdrive/My Drive/Colab Notebooks/data/omniglot.zip' -d Path(str_path)

But I get the same error.

How can I use the string root_dir with unzip?

My Python version is 3.6.9.

Answer 1

This is how I do it (without using !unzip command):

import os
import zipfile
from pathlib import Path

# Create destination folder if it doesn't exist.
Path(root_dir).mkdir(parents=True, exist_ok=True)

local_zip = '/content/gdrive/My Drive/Colab Notebooks/data/omniglot.zip'

zip_ref = zipfile.ZipFile(local_zip, 'r')

zip_ref.extractall(root_dir)
zip_ref.close()

Answer 2

Use {varname} syntax to pass Python variables into the shell.

import os

root_dir = '/tmp/omniglot/data/'
os.makedirs(root_dir, exist_ok=True)  # Create a target directory if doesn't exist

!unzip '/content/gdrive/My Drive/Colab Notebooks/data/omniglot.zip' -d {root_dir}

You can also use zipfile from standard library.

import zipfile

root_dir = '/tmp/omniglot/data/'
zip_file = '/content/gdrive/My Drive/Colab Notebooks/data/omniglot.zip'

with zipfile.ZipFile(zip_file, 'r') as zip_ref:
    zip_ref.extractall(root_dir)
