數據分割成塊，並添加號碼結果

Question

def multi(): 
    jobs = [] 
    r = open('raw.txt', 'r', 16777216).read().split('\n') 
    for i in r: 
     p = mp.Process(target=all, args=(i,)) 
     jobs.append(p) 
     p.start() 

raw.txt的每一行都是URL

請解釋我怎麼能修改多（）來

一）分裂raw.txt成塊（就是說，每10行），並應用所有（），以每塊和處理的行

b）退回數量/塊到底

謝謝

看看itertools包它有很多有用的東西。

>>> with open('input.txt', 'w') as f: 
... for i in xrange(998): 
...  f.write(uuid.uuid4().get_hex() + '\n') 
... 
>>> 
>>> from itertools import groupby, count  
>>> with open('input.txt', 'r') as f: 
...  samples = groupby(f, key=lambda k, line=count(): next(line)//100) 
...  for i in samples: 
...  print i 
...
