c - How to improve speed of saving serial data to file in Python -


i'm trying implement ramdump pc program can of ram data smart phone. code works, slow because of file writing. how can improve file-writing speed in python?

this part of code receive serial data:

while recv_num < tot_num:     remain_num = tot_num - recv_num     in range(512):         data = receive_qword()  # result=ser.read(size=8)         f.write(data)     recv_num = recv_num + 512

i have ramdump program written in c, , working on converting python. in c code function f_write(fil, ptr, size * count, &bwrite) works rapidly , seems operate bulk steam.

is there mechanism in python equivalent c mechanism?

try this

import array  while recv_num<tot_num: remain_num=tot_num-recv_num buffer = bytearray() in range(512):     buffer.extend(receive_qword()) # result=ser.read(size=8) f.write(buffer) #yep, after loop. recv_num = recv_num + 512

and sure need read in 8-packs? why not ser.read(512) ?
