centos安装pypy(含pypy下载地址)

今天ttlsa群友提问说pypy源码安装有问题，各种问题，有些人使用epel源yum安装，但是我发现我的epel没有pypy，在网上搜索了一番，找到了对应的rpm安装包，这边分享一下下载地址以及python与pypy的简单性能对比。

3. 测试pypy文章源自运维生存时间-https://www.ttlsa.com/python/install-pypy-on-centos/

# cat ttlsa_pypy.py
# -------------------------------
# DateTime：2013-10-08
# 站点: www.ttlsa.com
# -------------------------------
def 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__':
    main()

执行ttlsa_py.py文章源自运维生存时间-https://www.ttlsa.com/python/install-pypy-on-centos/

# time pypy ttlsa_py.py
1 1

2001002 4004009004004

real    0m5.585s
user    0m5.496s
sys     0m0.039s

4. python与pypy性能对比文章源自运维生存时间-https://www.ttlsa.com/python/install-pypy-on-centos/

# time python ttlsa_py.py      
1 1
....中间省略掉

real    0m32.719s
user    0m32.654s
sys     0m0.012s

python使用了32.719秒，pypy使用了5.58秒，相差了将近6秒文章源自运维生存时间-https://www.ttlsa.com/python/install-pypy-on-centos/
