Write lines longer than 80 chars in output file [Python]

I've got a pretty basic question. I'm using Python to calculate an n×12 vector

y = numpy.array([V1,V2,V3,V4,V5,V6,V7,V8,V9,V10,V11,V12])

which I append after each loop calculation.

My problem is that when I try to save it to a file or print it Python au开发者_运维百科tomatically breaks the result in three lines as my output usually exceeds 200 chars. Is there a way to supress this 80 char/line behavior? Many thanks in advance.

You can use numpy.savetxt() to save an array to a text file while controlling the formatting. To print it to the screen, you have different options to control the linewidth. One would be to call

numpy.set_printoptions(linewidth=200)

to set the linewidth to a higher value.
