Hi
I am trying to execute a command using os.system. this command lists
the number of nodes alive in a cluster. I would like to capture the
output in list/array in python. IS it possible.?/
Here is my command
gstat -a
node13 2 ( 0/ 56) [ 0.00, 0.00, 0.00] [ 0.0, 0.0,
0.1, 99.9, 0.0] OFF
node12 2 ( 1/ 63) [ 0.99, 0.97, 0.91] [ 46.6, 0.0,
3.7, 49.8, 0.0] OFF
node8 2 ( 1/ 59) [ 0.99, 0.97, 0.91] [ 47.5, 0.0,
2.8, 49.7, 0.0] OFF
node2 2 ( 1/ 59) [ 0.99, 0.97, 0.91] [ 46.6, 0.0,
3.7, 49.7, 0.0] OFF
node1 2 ( 1/ 59) [ 0.99, 0.97, 0.91] [ 46.6, 0.0,
3.7, 49.7, 0.0] OFF
node7 2 ( 1/ 58) [ 0.99, 0.97, 0.91] [ 49.8, 0.0,
0.6, 49.7, 0.0] OFF
node11 2 ( 1/ 59) [ 0.99, 0.97, 0.91] [ 46.6, 0.0,
3.8, 49.6, 0.0] OFF
node4 2 ( 1/ 59) [ 1.00, 1.00, 0.93] [ 46.6, 0.0,
3.7, 49.7, 0.0] OFF
node10 2 ( 1/ 59) [ 1.00, 1.00, 0.94] [ 46.7, 0.0,
3.7, 49.7, 0.0] OFF
node5 2 ( 1/ 59) [ 1.00, 1.00, 0.92] [ 49.8, 0.0,
0.4, 49.7, 0.0] OFF
node6 2 ( 1/ 59) [ 1.00, 1.00, 0.94] [ 49.5, 0.0,
0.9, 49.7, 0.0] OFF
I would like to have an array where each element contains the nodes
for example
a=[node13,node12,node2,node8,node1,node7,node 11]
any help would be appreciated
thanks
