File Read issue by using module binascii

[Jimmie He]

When I run the readbmp on an example.bmp(about 100k),the Shell is become to "No respose",when I change f.read() to f.read(1000),it is ok,could someone tell me the excat reason for this?
Thank you in advance!

Python Code as below!!

import binascii

def read_bmp():
    f = open('example.bmp','rb')
    rawdata = f.read()                       #f.read(1000) is ok
    hexstr = binascii.b2a_hex(rawdata)       #Get an HEX number
    bsstr = bin (int(hexstr,16))[2:]
    f.close()
    print('bin: ',bsstr,type(bsstr))
    return
