That's a syntax error.  You need to add parenthesis.

How about:

cond = (
     isinstance(left, PyCompare)
     and isinstance(right, PyCompare)
     and left.complist[-1] is right.complist[0]
}
py_and = (
          PyCompare(left.complist + right.complist[1:])
     if   cond
     else PyBooleanAnd(left, right)
)
