i'm tring to generate an array reading a txt file from internet.
my target is to use python instead of matlab, to replace this steps in matlab :
i'm using this code :
urllib.urlretrieve('http://www.cdc.noaa.gov/Correlation/amon.us.long.data', 'file.txt') a = np.loadtxt('file.txt', skiprows=1)
but it fails becouse of the txt description at the end of the file,
do you know if exist a way to skip the X lines at the end,
something like "skipmultiplerows='1,-4'" (to skip the first and the last 4 rows in the file)
or i have to use some sort of string manipulation (readlines?) instead ?
