Pypy 确实比较快

centos 安装命令 yum -y install pypy-libs pypy pypy-devel

装好了以后测试了一下，用下面这段代码

import timedef check(num):     a = list(str(num))     b = a[::-1]     if a == b:         return True     return False  def main():    all = xrange(1,10**7)    for i in all:        if check(i):            if check(i**2):                print i,i**2  if __name__ == '__main__':        begin = time.time()    main()    print time.time()-begin

1核1G的机器上试了下:

python 22.48 秒

pypy 3.7 秒
