Python Code Acceleration（Python代碼加速）

對於Python的代碼執行效率較低的問題，參考博客：https://developer.51cto.com/art/201809/583695.htm進行相應的測試。

參考代碼如下：

from numba import jit
import time

def foo(x,y):
  tt = time.time()
  s = 0
  for i in range(x,y):
    s += i
  print('Time used: {} sec'.format(time.time()-tt))
  return s

print(foo(1,100000000))

輸出時間：

Time used: 3.7836766242980957 sec
4999999950000000

加入代碼：

from numba import jit
import time
@jit
def foo(x,y):
  tt = time.time()
  s = 0
  for i in range(x,y):
    s += i
  print('Time used: {} sec'.format(time.time()-tt))
  return s

print(foo(1,100000000))

輸出時間：

Time used: 0.02804708480834961 sec
4999999950000000

這個時間很可觀了，very very fast！！！對於時間的進一步優化以及使用明天再來詳細研究。
