error in loading data into the code

[nakisa]

hello , I have started python last week,so maybe my question is a bit
stupid.
I got this error in my simple python code while trying to load data
into the code. I have added this libaraies
from pylab import *
from scipy import *
import matplotlib.mlab as mlab
from numpy import *
from scipy import optimize

but get this following error :

/usr/lib/pymodules/python2.6/matplotlib/mlab.py:1267:
DeprecationWarning: use numpy.loadtxt
  warnings.warn("use numpy.loadtxt", DeprecationWarning)  # 2009/06/13

any idea ?

thanks,Nakisa
