I have data I want to plot and analyse, looking like:



0101 

1  3

2  4

3  6


I use skip_header in genfromtxt to load the file 2 column data, however I also need the header for reference.



Is there a way to get the header back?






python numpy genfromtxt

  • Use a regular Python file read to get that line,

  • For genfrontxt this isn't a valid column header. So are right to skip it. And there's no provision for saving or recording skipped lines. Why should there be?

I am not sure that this is implemented in numpy.genfromtxt(). You may have to call the function twice, once for the header, and a second time for the data. Or you may want to have a look at the functions offered by pandas, such as read_table.

    You can try with pd.read_csv:



    data = pd.read_csv(filename, sep=" ")


    So that the first line is read as header
