You could show an _example_ codeString, though. That would have greatly
simplified the diagnosis.

Maybe you can get away with a simple expression:

>>> from math import *
>>> codeString = "sin(0.5) + 23"
>>> eval(codeString)
23.479425538604204

If not, try

>>> codeString2 = "a=0.5\nb=23\nreturn sin(a) + b"
>>> funcString = "def f():\n    " + "\n    ".join(codeString2.split("\n"))
>>> funcString
'def f():\n    a=0.5\n    b=23\n    return sin(a) + b'
>>> exec funcString
>>> f()
23.479425538604204
>>>
