# Finding Re() and Im() for complex numbers

Hey guys,

Is there a way to find the real and imaginary parts of a complex number in Sage? If so, how is it done?

Thanks.

.real() for real part .imag() for imaginary part

For eg.

```
(3+i*4).real()=3
(3+i*4).imag()=4
```

real_part(z) and imag_part(z) also work.
