loadtxt using numpy in python

Hi

I have data files that has blocks of data (see the file attached). I need to read only the first block of data in to an array (index 0) using python, at this point i load all the data. I can do this by checking the value of idex in the array data after I load them, but I was wondering if there is any easy way to do this.

I use 'loadtxt' in numpy to load the data.


thanks in advance
