For each virtualenv I keep a requirements file that lists all the packages I have installed including indirect dependencies, and with the exact version numbers. I update this file whenever I make changes to a virtualenv. Then when a virtualenv stops working for any reason I just regenerate it. To export a requirements file you can use this command (note this must be done on a working virtualenv): $ pip freeze > requirements.txt To populate a virtualenv from a requirements file use this command after activating it: $ pip install -r requirements.txt I hope this helps.

Yes, I've definitely requirements.txt?d all my current virtualenvs. Not having up-to-date requirements.txt for the virtualenvs I had to re-create, I was able to figure out what apps were installed by inspecting the [virtualenvs root directory]/[virtualenv]/lib/python2.7/site-packages directory of each of the virtualenvs. Actually, I was able to cherry-pick/copy the .py files from the old /site-packages/ into the new. It was just a Python 2.7.5 to 2.7.6 transition and so this seems to be have worked. Any bigger of a Python version jump, and who knows ?

Brew's method of making a new site-packages results in the locations changing, with this result. If I'm not mistaken it might be a decent suggestion to the homebrew python maintainers to make patch upgrades smoother.

I'll be offering another hardcore Python course this summer near the San Francisco airport. If you're somewhat new to or have some Python experience under your belt already but want to fill-in the holes, this course is for you. Why take a real course when you can learn Python online or by reading books? Well, my goal isn't to teach Python syntax, which you can from any teacher, live or online, or from giant books. My job is to create great Python developers and removing the roadblocks that impede your path to getting there. This intensive course is based on my "Core Python" (http://corepython.com) books and is made up of 3 full days complete with lectures and several hands-on coding labs per day. t's also a great excuse to coming to beautiful Northern California for a summer vacation and just a 1-hour flight from PDX! Groups and development teams are welcome as well as individuals. I do more private gigs and fewer of these public courses lately, so please come join if you can... my next public intro/intermediate course may not be for awhile, so I'm hoping to meet some of you this time around! Sign up soon... there's a special earlybird rate for the rest of this month before going up to the regular rate after that. More details and registration at http://cyberwebconsulting.com as well as in the ad: http://goo.gl/pyJseQ I'm no fan of spam, so I'll only send out one last reminder as the date gets closer... say around the end of June.

WHEN: Friday May 30th 4:30pm - 6:00pm WHERE: Portland State, FAB 86-01 DESCRIPTION: Flask is a small and easy-to-use, yet fully featured open source web framework written in Python. It is considered a micro-framework, but don't let the "micro" part fool you; Flask can do everything the others can do, many times in a simpler, leaner way. This presentation will introduce you to Flask through several examples that you can download and try. PRESENTER: Miguel Grinberg has over 25 years of experience as a software engineer and leads a team of engineers that develop software for the video broadcast industry. He is the author of the O'Reilly book "Flask Web Development", and blogs at http://blog.miguelgrinberg.com about a variety of topics including web development, robotics, photography, and the occasional movie review. He lives in Portland, Oregon with his wife, four kids, two dogs, and a cat. Follow @miguelgrinberg on Twitter.
