我有1gb的大文件,所以我尝试了上面的方法来读取,它将值打印为字符串,但不能读取为json,因为它的大小为2k
我试过以下代码
import json
def read_in_chunks(file_object, chunk_size=2048):
"""Lazy function (generator) to read a file piece by piece.
Default chunk size: 2k."""
while True:
data = file_object.read(chunk_size)
if not data:
break
yield data
f = open('productfeed.json','r')
for piece in read_in_chunks(f):
print piece
得到这样的错误“ ValueError:从第1行第1012行开始的未终止字符串(字符1011 ) “
不知道如何继续进行,请有人帮助我,不允许使用 ijson
