This should get you started:
vars = """dof = 8
elements = 10
mesh_dof = 300"""
for line in vars.split("\n"):
exec (line)
print dof,elements,mesh_dof
You should be careful exec'ing things though, so maybe:
vars = """dof = 8
elements = 10
mesh_dof = 300"""
for line in vars.split("\n"):
try:
k,v = line.split(" = ")
exec (line)
except:
# doexn't parse out as tuple w/ interspersed =
pass
print dof,elements,mesh_dof
is safer. I'm sure there's still a hole in that, I just
don't see it right now.
