Hello,

Which version of Python is preferred for running the sample codes?

In python version 2.7, the below lines fail to execute...

  • cat_data = array(['male', 'female', 'male', 'male', 'female', 'male', 'female', 'female'])

  • categories = unique(data)

  • features["sqrt_Fare"] = sqrt(data["Fare"])



  • i think it will be good if code samples are embedded into the respective chapters along with all relevant 'import' statements mentioned in it.

    Hi,

    That example assumes that you've imported everything from pylab:

    from pylab import *
    


    If you use ipython, you can get all of this with this line instead:

    %pylab inline
    


    Take a look at the examples in our Github repo for more detailed usage:

    Hope that helps! Otherwise, please copy/paste the error message in here so I can understand it further.

    the sample code works with this line included:

    from pylab import *

    Thanks for the clarification and the quick response.
