Python3 and pandas

there is a python3-pip which will install pip-3.3 instead of pip. the pip-3.3 will install the pandas package into python3.3

You may just install it by sudo apt-get install python3-pandas if you'd prefer a system-wide installation

Update

As mentioned below, pandas is now available for python 3.3, 3.4 and 3.5 source

For system wide install use:

sudo apt-get install python3-pandas

Original:

If this information http://packages.ubuntu.com/precise/python/ is correct there is no pandas package for Python 3. You can install current pandas using virtualenv:

apt-get install python-virtualenv virtualenvwrapper

mkvirtualenv -p python3 pandas_env
pip install pandas

Generally it is a good idea to create separate virtual environments when working with Python and to avoid manual messing with system wide packages.
