1.首先匯入模組 redis
沒有的話需要下載

pip install redis
pip install time
pip install sys

2.程式碼如圖所示：

import redis
import sys
import time
try:
	redis_conn=redis.ConnectionPool(host='xxx.xxx.xxx.xxx',port=xxxx,db=0)
	r = redis.StrictRedis(connection_pool=redis_conn)
expect Expection as e:
	print
 
("連線redis資料庫失敗，檢查連線！！")
	print(e)
	sys.exit()
time_start=time.time()
a = 0
for i in r.scan_iter(match="*", count=1000):
# match用來匹配尋找key，*代表所有
# count代表每次取多少
    print(i)
    a += 1
    if a == 2000000:
        break
time_stop = time.time()
print("一共%s條資料" % a)
print("一共用了：%0.2f"
 
 % (time_stop - time_start))

執行結果：
