python array module

← 🏠

Write a python program that loads 10 million floats into an array, and writes them to disk.

 1from array import array
 2from random import random
 3
 4def main():
 5    floats = array('d', (random() for i in range(10**7)))
 6    fp = open('floats.bin', 'wb')
 7    floats.tofile(fp)
 8    fp.close()
 9    floats2 = array('d')
10    fp = open('floats.bin', 'rb')
11    floats2.fromfile(fp, 10**7)
12    fp.close()
13    print(floats == floats2)
14
15main()

Output:

1real  0m2.989s
