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)
'''
