import sys
from cclib.parser import ccopen
from cclib.bridge import makeopenbabel
import openbabel as ob
parser =3D ccopen(sys.argv[1])
data =3D parser.parse()
distort =3D data.atomcoords[0] - data.vibdisps[0]
obmol =3D makeopenbabel(distort, data.atomnos)
obconv =3D ob.OBConversion()
ok =3D obconv.SetOutFormat("XYZ")
obconv.WriteFile(obmol, "distorted.xyz")`
这个简单的 python 脚本给出如下语法错误
"test.py", line 7
> parser = 3D ccopen(sys.argv[1])
> ^
>SyntaxError: invalid syntax"
任何人都可以帮助解决这个问题。谢谢
