Scipy resample, fourier method explanation

How does Scipy resample work?

Scipy docs has this in method description: Resample x to num samples using Fourier method along the given axis. The resampled signal starts at the same value as `x` but is sampled with a spacing of ``len(x) / num * (spacing of x)``. Because a Fourier method is used, the signal is assumed to be periodic.
