With vanilla Python:
>>> vt = [0] * 20
>>> for i, v in enumerate(vt):
... if 4 <= i < 8 or 13 <= i < 16:
... vt[i] = .17
...
>>> vt
[0, 0, 0, 0, 0.17, 0.17, 0.17, 0.17, 0, 0, 0, 0, 0, 0.17, 0.17, 0.17, 0, 0,
0, 0]
With vanilla Python using slices:
>>> vt = [0] * 20
>>> vt[4:8] = [.17]*4
>>> vt[13:16] = [.17]*3
>>> vt
[0, 0, 0, 0, 0.17, 0.17, 0.17, 0.17, 0, 0, 0, 0, 0, 0.17, 0.17, 0.17, 0, 0,
0, 0]
With numpy:
>>> vt = numpy.zeros(20)
>>> vt[4:8] = vt[13:16] = .17
>>> vt
array([ 0. , 0. , 0. , 0. , 0.17, 0.17, 0.17, 0.17, 0. ,
0. , 0. , 0. , 0. , 0.17, 0.17, 0.17, 0. , 0. ,
0. , 0. ])
