String in Luatex

String in Luatex

[luigi scarso]

The following macro is wrong:
\def\TestC{%
\directlua0{%
\obeyspaces \obeylines
code =[[
class Test(object):
  def __init__(self):
    self.a=[0,3,81,2,-1]
    self.b=self.a[:]
    self.a.sort()

  def get(self):
    return self.a,self.b
]]
}}

! LuaTeX error [string "luas[0]"]:1: unexpected symbol near '\'.
\TestC ...def get(self): return self.a,self.b ]] }


I must preserve spaces and newlines.

Any idea ?
Thanks in advance

As a last resorse to preserve spaces

No, it doesn't work for my needs because it doesn't preserve spaces and newline.
This works, after putting code in testD.lua
\def\TestD#1{%
\directlua0{dofile('testD.lua')}%
}
