Hi ,
I have a question about python build-in function 'eval ' , please check out
the example code below :
## create a polySphere , default name : 'pSphere1'
import pymel.core as pm
from pymel.core import nt
# initialize a pymel transform node
pymelShpere = pm.PyNode('pSphere1')
# put it to a dict
testDict = {0:pymelShpere}
# convert it to str which can be stored as string in file basic data
strMark = str(testDict)
# now read it back , if scene has the pShere1 , it will work perfectly
newDict = eval(strMark)
# now delete the pShpere1 , and try to convert data to dict , failed
because the pymel nt will try to initialize the string 'pShere1' to pymel
node
newDict =eval(strMark)
My question : if I have lots of nodes store in a string data which convert
from dict , is there a way to just make it out , just ignore error part or
if node not exists it just convert from nt to string name ?
if pSphere2 not exist then return
{0:nt.Transform('pSphere1'), 1:'pSphere2' }
Any idea is very much welcome , big thanks !!!
