Please clarify in resolving this error

I can see parenthesis is not closed for below statement in your code

L=(len(x)/2*np.log(2*np.pi)+len(x)/2*np.log(sigma**2)+1/(2*sigma**2)*sum((y-y_exp**2)))

Hope this is enough...

1	L=(len(x)/2*np.log(2*np.pi)+len(x)/2*np.log(sigma**2)+1/(2*sigma**2)*sum((y-y_exp**2)))

Hope this is enough...
