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")

What does your output look like when you do this? – Matt Aug 09 '13 at 06:28 — Matt, Aug 09 '13 at 06:28
File has one line like as 23 24 25 ... – Serenity Aug 11 '13 at 01:00 — Serenity, Aug 11 '13 at 01:00

Assuming your array to save is t:

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

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")
