The`extractall()` method for ZipFile objects extracts all the files and folders from a ZIP file into the current working directory.
36+
37+
```python

... example_zip.extractall()
40+
```
41+
42+
The`extract()` method for ZipFile objects will extract a single file from the ZIP file:
43+
44+
```python
45+
>>>with zipfile.ZipFile('example.zip')as example_zip:
46+
...print(example_zip.extract('spam.txt'))
47+
...print(example_zip.extract('spam.txt','C:\\some\\new\\folders'))
48+
...

# 'C:\\spam.txt'

# 'C:\\some\\new\\folders\\spam.txt'
51+
```

##Creating and Adding to ZIP Files
54+
55+
```python

59+
... new_zip.write('spam.txt',compress_type=zipfile.ZIP_DEFLATED)

```

This code will create a new ZIP file named new.zip that has the compressed contents of spam.txt.

```
76+

78+
79+
```python
80+
>>>import datetime
81+
>>>import zipfile
82+
>>>
83+
>>>with zipfile.ZipFile(archive_name)as zf:
84+
...for infoin zf.infolist():

...print(f'Compressed :{info.compress_size} bytes')
93+
...print(f'Uncompressed:{info.file_size} bytes')
