Hi,
I'm new to python programming so this question will probably be a no brainer for the experienced programmer. I'm trying to create a 10x10 array of zeros and then framing it with a border of ones. Output should look like this: [[ 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1.] [ 1. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 1.] [ 1. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 1.] [ 1. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 1.] [ 1. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 1.] [ 1. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 1.] [ 1. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 1.] [ 1. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 1.] [ 1. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 1.] [ 1. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 1.] [ 1. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 1.] [ 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1. 1.]] This is the code I've written: a = np.ones ((1,10)) print a b = np.zeros ((10,10)) print b c = np.vstack ((b,a)) print c This is my output: [[ 1. 1. 1. 1. 1. 1. 1. 1. 1. 1.]] [[ 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.] [ 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.] [ 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.] [ 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.] [ 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.] [ 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.] [ 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.] [ 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.] [ 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.] [ 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.]] [[ 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.] [ 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.] [ 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.] [ 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.] [ 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.] [ 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.] [ 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.] [ 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.] [ 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.] [ 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.] [ 1. 1. 1. 1. 1. 1. 1. 1. 1. 1.]]? As you can see I have too many zeros once I stack them and don't have the ones framing the sides vertically. Any guidance on where I'm going astray? Much appreciated, A.B. _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
