2. Cool stuff!
• File formats
• Compression
• Algorithms and data structures
• Networking
• Package distribution
• All built in!

3. File formats

4. CSV

5. JSON
• Simple python data structures to/from JSON strings
• Use in conjunction with urllib2 for great success!

6. XML
• Three options:
- DOM (familiar to Javascript developers)
- SAX (event driven, big data)
- ElementTree (feels like Python)

12. Compression
• GZip compression
-
• ZipFile
- Access zip file’s contents
- Put data in:
- Get data out:

13. Algorithms and data structures

14. Algorithms and data structures
• : Functional programming
• and : A great combination

15. Algorithms and data structures

16. Algorithms and data structures
• : Useful data structures
•
• (you probably want this a LOT)

17. Algorithms and data structures
• : C-style data structures
• Equivalent to:

18. Algorithms and data structures
• : Memory-efficient homogenous arrays
• You probably want , but this is nice too

19. Networking
• module for low-level TCP programming
• Probably care more about HTTP though

20. Networking (HTTP)
• Kind of messy organization in Python 2.X
• Fetching:
• Parsing:

21. Package distribution
• Distutils
• You can provide Windows installers (.exe or .msi) for
your code libraries
• Semi-automatic compilation of C/C++ libraries

22. Package distribution
• Layout:
•
• Setup.py:
