Example 14 - Python results

A number of tools returns results as python string. These results contains array of scalars or points.

A typical result string looks like this:

((190.41,208.87),(190.61,225.7),(190.9,242.52),(191.18,259.35),(191.34,276.18))

Example:

pointStr = GetValue('Edges.Edge points')

print ' python string : ', pointStr
points = eval(pointStr)

print ' points as list ', points

print ' length of list : ', len(points[0])

print ' first element : ',points[0][0]
print ' x : ',points[0][0][0]
print ' y : ',points[0][0][1]

Output in the console windows:

python string : (((190.41,208.87),(190.61,225.7),(190.9,242.52),(191.18,259.35),(191.34,276.18),(191.5,293.28),(191.85,310.3),(191.98,327.08),(192.08,343.8),(192.35,360.52),(192.59,377.24),(192.76,393.89),(192.86,410.55),(193.03,427.3),(193.34,444.04),(19
