python--字典dict切割

需求：有一個字典，有三千多個key，需要對其進行字典切割，切割後存入列表（list）中。

import multiprocessing  # 加載多進程庫
import itertools   #加載字典切割庫

from requests.adapters import HTTPAdapter

# 拼接url，返回一個字典url_dict，該字典長度有三千多個

            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 

# 運行主體函數

    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"區不正常")
