I wanted to load tables from a mysql database and to run analyses on them. Had already done some analysis on R, but wanted to make them portable to a website, and thought that python would be better suited for that.
The version of pandas currently shipped with Ubuntu is outdated 0.7. I had to use another method to get a newer version.
Pandas source code is currently hosted on GitHub at: http://github.com/pydata/pandas
After a
sudo apt-get install python-pip
I installed pandas via ``pip``::
pip install --upgrade pandas
Still my script with
dtf = pandas.io.sql.read_frame("SELECT * FROM Table", db)
was returning an error, expecting list got tuple.
And pandas.__version__ was still at 0.7.0.
I uninstalled the python-pandas package.:
sudo apt-get remove python-pandas
And ran again
sudo pip install pandas
After that, pandas.io.sql.read_frame() was working as expected.
And dtf.head() showed me a proper vue of the table.
Columns can be selected with dtf.columnname or dtf['columnname'].
