I was trying to create a csv file that stores random number data used in TensorFlow.

prep_data.py

import numpy as np
import random

numdata=10
x_data = np.random.rand(numdata)
y_data = np.sin(2*np.pi*x_data) + 0.3 * np.random.rand()

for xs, ys in zip(x_data, y_data):
	print '%.5f, %.5f' % (xs, ys)

result
