jit提升python执行效率

使用jit提升python效率

需要第三方库：pip install numba

import datetime
from numba import jit

@jit(nopython=True)

def noThreading(n):
    sum=0
    for i in range(n):
        sum = sum +i

if __name__ == '__main__':
    start = datetime.datetime.now()
    noThreading(100000000)
    end = datetime.datetime.now()
    # print(start,end)
    print((end-start).total_seconds() )
