Set up encoding. Modified x3d.py at head of file:
#!/usr/bin/python
# -*- coding: utf-8 -*-
Now getting this:
python HelloWorld.py
Traceback (most recent call last):
File "HelloWorld.py", line 23, in <module>
from x3d import *
File
"/home/coderextreme/X3DJSONLD/src/main/python/net/x3djsonld/data/x3d.py",
line 1992
print('* isValidMFColor tuple ' + str(each) + ' has length ' +
str(len(each)) + ' which is not a multiple of MFColor().TUPLE_SIZE()=' +
str(MFColor().TUPLE_SIZE()) + ' for value=' + str(value), flush=True)
^
SyntaxError: invalid syntax
