Complex number and "TypeError: 'float' object is not callable"

[Alasdair]

Here's the error:

c=complex((sqrt(3)+2*I)^4)
imag(c)

returns

"TypeError: 'float' object is not callable"

So - how do I obtain the imaginary part of c?

Thanks,
Alasdair

c.imag

Our imag() function should really know about Python complex variables...

Thanks - being a beginner I thought that c.imag() was the only
allowable syntax; I didn't know c.imag was allowed.

I agree. This is http://trac.sagemath.org/sage_trac/ticket/5420 and is
very easy, low-hanging fruit for anyone that wants to learn how to
contribute to Sage :).

It's not in general, only for the Python complex type.
