python--字典dict切割

需求：有一个字典，有三千多个key，需要对其进行字典切割，切割后存入列表（list）中。

import multiprocessing  # 加载多进程库
import itertools   #加载字典切割库
import time
from requests.adapters import HTTPAdapter
import requests
# 拼接url，返回一个字典url_dict，该字典长度有三千多个
domains=".x.xxx.com/data/newworldkill"

        for i in list[0].split(","):
            url="http://s"+str(i)+domains
            dbnum=list[2]
            url_dict[url]=dbnum
            #get_status(url,dbnum)
# 分割字典
def splitDict(d):
    lists = []
    n = len(d)//100 # length of smaller half
    i = iter(d.items()) # alternatively, i = d.iteritems() works in Python 2
    for x in range(100):
        d = dict(itertools.islice(i, n)) # grab first n items
        lists.append(d)
    return lists 

# 运行主体函数
def run(url_dicts):
    headers = {
    'Connection': 'close',
    }
    for value,key in url_dicts.items():
        status_code = requests.get(value,headers=headers).status_code
        if str(status_code) == "200":
            print(value+"|"+str(key))
        else:
            print(str(key)+u"区不正常")
if __name__ == '__main__':
# 多进程运行程序
    for i in range(100):
        lists = splitDict(url_dict)
        p = multiprocessing.Process(target=run,args=(lists[i],))
        p.start()```
