python 文件转成16进制数组的实例

如下所示：

#! /usr/bin/python2# coding=utf-8import numpyimport binasciiif __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)  '''
