try to make my triple nested loop working. My code would be: c = 4 y1 = [] m1 = [] std1 = [] while c <24: c = c + 1 a = [] f.seek(0,0) for columns in ( raw.strip().split() for raw in f ): a.append(columns[c]) x = np.array(a, float) not_nan = np.logical_not(np.isnan(x)) indices = np.arange(len(x)) interp = interp1d(indices[not_nan], x[not_nan], kind = 'nearest') p = interp(indices)
N = len(p) dt = 900.0 #Time step (seconds) fs = 1./dt #Sampling frequency KA,PSD = oned_Fourierspectrum(p,dt) # Call Song's 1D FS function time_axis = np.linspace(0.0,N,num = N,endpoint = False)*15/(60*24) plot_freq = 24*3600.*KA #Convert to cycles per day plot_period = 1.0/plot_freq # convert to days/cycle fpsd = plot_freq*PSD d = -1 while d <335: d = d + 1 y = fpsd[d] y1 = y1 + [y] m = np.mean(y1) m1 = m1 + [m] print m1 -------------------------------------------------------------------------------- My purpose is make a list of [mean(fpsd[0]), mean(fpsd[1]), mean(fpsd[2]).. mean(fpsd[335])]. Each y1 would be the list of fpsd[d]. I check it is working pretty well before second while loop and I can get individual mean of fpsd[d]. However, with second whole loop, it produces definitely wrong numbers. Would you help me this problem? -- http://mail.python.org/mailman/listinfo/python-list
