Calculation of Steel Design, CPython3

Hi @sanzoghenzo,
Thank you for your reply.
I changed the code, but it has an error: " name ‘BindingFlags’ is not defined [’ File “”, line 65, in \n’, ’ File “”, line 23, in newm\n’]", see figure below.

Could you help me to check what is wrong with the code? Because I would like to get the value of Nbyrd, the same way I get the value of the ratio.

Thank you in advance.

Best regards,
Stefany
