Fast fourier transform python

# This is from the question
from scipy.fftpack import fft

# Number of samplepoints
N = 600

# Sample spacing
T = 1.0 / 800.0
x = np.linspace(0.0, N*T, N)
y = np.sin(50.0 * 2.0*np.pi*x) + 0.5*np.sin(80.0 * 2.0*np.pi*x)
yf = fft(y)

What is fourier transform in python

fft ) Fourier analysis is a method for expressing a function as a 
sum of periodic components, and for recovering the signal from those components. 
When both the function and its Fourier transform are replaced with
discretized counterparts, it is called the discrete Fourier transform (DFT).
