How does Numpy fft work?

The fft function which uses the functionality of the SciPy package works in a way that, it uses the basic data structures that are used in the numpy arrays, in order to create a module that is required for scientific calculations and programming.

How to extract frequency from fft Python?

We can obtain the magnitude of frequency from a set of complex numbers obtained after performing FFT i.e Fast Fourier Transform in Python. The frequency can be obtained by calculating the magnitude of the complex number. So simple ab(x) on each of those complex numbers should return the frequency.
