python 文件转成16进制数组的实例
如下所示:
#! /usr/bin/python2 # coding=utf-8 import numpy import binascii if __name__=='__main__': #my_matrix = numpy.loadtxt(open("d:\\local.pcm", "rb"), delimiter=",", skiprows=0) #print my_matrix with open('d:\\local.pcm', 'rb') as f: all = f.read() with open('d:\\aa.txt', 'w') as f: f.write("char buf[]={") for d in all: #e = "%02s," % hex(ord(d)) #print binascii.b2a_hex(d) e = "0x%s," % binascii.b2a_hex(d) #print e f.write(e) #L = f.tell() #f.seek(L-1,0) f.seek(-1, 2) f.write("};") ''' for i in all: #print type(i),i,int('0x10', i) x = "0x%s" % i print type(x),x b = binascii.b2a_hex(i) c = "0x%s" % b print b,type(b),c, type(c) '''
