Python: moving to a new computer

Question

I'm moving from a computer with windows xp to one with windows 7 (64 bit) and I want to install Python on the new machine. I'm currently using python 2.7 and 3.2 and a bunch of packages

1) Should I install the 64 bit versions?

2) How can I tell which packages I currently have, so that I can get those for the new machine?

If these are duplicates (my search skills seem to be failing), please point me to the threads where they're discussed.

Answer 1

You can use pip now for this purpose.

using pip list will give you a list of the packages that you have installed and the versions.

You could also use pip freeze and then copy the output of this to a file and then use this as a requirements files so you can install those exact modules and versions again on the new computer. More information on pip is here is here

but to install from a requirements files you would use

pip install -r requirements.txt
