还有一个解决方案

def make_chunks(data, chunk_size): 
    while data:
        chunk, data = data[:chunk_size], data[chunk_size:]
        yield chunk

>>> for chunk in make_chunks([1, 2, 3, 4, 5, 6, 7], 2):
...     print chunk
... 
[1, 2]
[3, 4]
[5, 6]
[7]
>>> 

简单而优雅

L = range(1, 1000)
print [L[x:x+10] for x in xrange(0, len(L), 10)]

或者如果您愿意：

def chunks(L, n): return [L[x: x+n] for x in xrange(0, len(L), n)]
chunks(L, 10)

我意识到这个问题已经过时了（在谷歌上被它绊倒了），但肯定像下面这样的问题比任何复杂的建议都要简单和清晰得多，而且只使用切片：

def chunker(iterable, chunksize):
    for i,c in enumerate(iterable[::chunksize]):
        yield iterable[i*chunksize:(i+1)*chunksize]

>>> for chunk in chunker(range(0,100), 10):
...     print list(chunk)
... 
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
[10, 11, 12, 13, 14, 15, 16, 17, 18, 19]
[20, 21, 22, 23, 24, 25, 26, 27, 28, 29]
... etc ...

与任何可迭代的内部数据是生成器对象（不是列表）一个衬垫

In [259]: get_in_chunks = lambda itr,n: ( (v for _,v in g) for _,g in itertools.groupby(enumerate(itr),lambda (ind,_): ind/n))

In [260]: list(list(x) for x in get_in_chunks(range(30),7))
Out[260]:
[[0, 1, 2, 3, 4, 5, 6],
 [7, 8, 9, 10, 11, 12, 13],
 [14, 15, 16, 17, 18, 19, 20],
 [21, 22, 23, 24, 25, 26, 27],
 [28, 29]]

这是一个生成大小均匀的块的生成器：

def chunks(lst, n):
    """Yield successive n-sized chunks from lst."""
    for i in range(0, len(lst), n):
        yield lst[i:i + n]

import pprint
pprint.pprint(list(chunks(range(10, 75), 10)))
[[10, 11, 12, 13, 14, 15, 16, 17, 18, 19],
 [20, 21, 22, 23, 24, 25, 26, 27, 28, 29],
 [30, 31, 32, 33, 34, 35, 36, 37, 38, 39],
 [40, 41, 42, 43, 44, 45, 46, 47, 48, 49],
 [50, 51, 52, 53, 54, 55, 56, 57, 58, 59],
 [60, 61, 62, 63, 64, 65, 66, 67, 68, 69],
 [70, 71, 72, 73, 74]]

对于Python 2，使用xrange代替range：

def chunks(lst, n):
    """Yield successive n-sized chunks from lst."""
    for i in xrange(0, len(lst), n):
        yield lst[i:i + n]

下面是一行理解列表。不过，上面的方法更可取，因为使用命名函数使代码更容易理解。对于Python 3：

[lst[i:i + n] for i in range(0, len(lst), n)]

对于Python 2：

[lst[i:i + n] for i in xrange(0, len(lst), n)]

另一个更明确的版本。

def chunkList(initialList, chunkSize):
    """
    This function chunks a list into sub lists 
    that have a length equals to chunkSize.

    Example:
    lst = [3, 4, 9, 7, 1, 1, 2, 3]
    print(chunkList(lst, 3)) 
    returns
    [[3, 4, 9], [7, 1, 1], [2, 3]]
    """
    finalList = []
    for i in range(0, len(initialList), chunkSize):
        finalList.append(initialList[i:i+chunkSize])
    return finalList
