print getproperty("auxiliaryinfo","models", 1,"symmetryOperations")
should do it. You'll have to parse that.
Or you can use
show symmetry
Symmetry Information:
model #1.1; name=global
Spacegroup: P 32 2 1
Number of symmetry operations: 6
Symmetry Operations:
x,y,z
y,x,-z-1/3
-y,x-y,z-1/3
-x,-x+y,-z+1/3
-x+y,-x,z+1/3
x-y,-y,-z
and parse that, for example:
x = script("show symmetry").split("operations: ")[2].split("\n")[1]
print x
This takes the next word in the line after the "operations: " text,
which will be the number of symmetry operations.
