read_table € symbol
Dear all,
I'm trying to read a txt file with read_table but in the file there are some
string that contain the € symbol and the procedure returns me an error.
I tried with encoding='utf-8' but the problem is still there:
pd.read_table('filename.txt', sep=';', encoding='utf-8')
Anyone can help me?
Many thanks in advance
Davide

Re: statsmodels.api
Oscar you are right! The problem was Numpy! I re-installed it using an executable that I downloaded from: http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy I don't remember if previously I installed it using another source. However the problem now is disappeared! Many thanks! Davide -- https://mail.python.org/mailman/listinfo/python-list

Re: ipython
I did not see the massage when installation finisched. Sorry! Many Thanks!!! The IPython installer actually mentions this when it finishes installing: Distribute (setuptools) is required to create Start Menu items. Re-run this installer after installing distribute to get Start Menu items. You can grab the setup for distribute from: http://python-distribute.org/distribute_setup.py If your Python 3.3 installation is part of your PATH, you simply do: python3 distribute_setup.py install When it's finished, run the IPython installer again and you'll find it now creates a start menu shortcut for you. -- http://mail.python.org/mailman/listinfo/python-list

Hi, I work with Python 3.3. I downloaded an IPython executable version from http://www.lfd.uci.edu/~gohlke/pythonlibs/ I installed it but no shortcut appears in my start menu. How can I launch it or alternatively is there some other free source of executable file for Windows 7? Many Thanks -- http://mail.python.org/mailman/listinfo/python-list
