[Error] Decomposing a surface 'Eistute' using Python as symbolic engine

[foongminwong]

I'm trying to decompose a surface called "Eistute" and got the following error:

  File "python_deflate.py", line 38
    function f_2_1, f_2_2, f_2_3, f_2_4, f_2_5, f_2_6, f_2_7, f_2_8, f_2_9, f_2_10, f_2_11, f_2_12;
                 ^
SyntaxError: invalid syntax
ERROR: Trying to redefine f_2_1 in system statement 21.

Bertini will now exit due to this error.```
