arrays - 2d numpy array to text file

Question

I have a 3D-array storing temperature data. And me want to put it to text file in one single line. Need to re-write this code in pythonic way.

    for jn in range(X1, X2):
        for jm in range(Y1,Y2):
            fl.write(str((t[jn,jm] - 273.1).astype(int))+" ")
    fl.write("\n")

Answer 1

假设您要保存的数组是t：

t.tofile('yourfile.txt',sep=" ",format="%s")

Answer 2

values = ("{0:.0f}".format(t[i,j]-273.1) 
                for i in xrange(X1, X2) 
                for j in xrange(Y1,Y2))
line = " ".join(values)
fl.write(line + "\n")
