Class zipfile.ZipFile has two methods for adding data to a zipfile: 'write' and 'writestr'. The former has a "compression_type" argument that can be used to specify the compression to be used. That latter doesn't have that argument. Could a "compression_type" argument be added to "writestr" as well? I regularly create zipfiles from scratch using the writestr method to add content and currently have to modify the 'compression' attribute of the zipfile object to control compression and that leads to ugly code. The other alternative is to use a ZipInfo object as the archive-name of the newly added file, but that leads to even uglier code.

The patch looks ok. It can certainly go in trunk, as for 3.1 it's up to Benjamin to decide. Note: the docs should state that the new argument appeared in 2.7.
