Python 十六进制整数与ASCii编码字符串相互转换方法

# -*- coding: utf-8 -*-
import binascii
#16进制整数转ASCii编码字符串
a = 0x665554
b = hex(a) #转换成相同的字符串即'0x665554'
b = b[2:]  #截取掉'0x'
c = binascii.a2b_hex(b) #转换成ASCii编码的字符串
print("a:%x, b:%s,c:%s" %(a,b,c))
print type(a)
print type(b)
print type(c)

a:665554, b:665554,c:fUT
<type 'int'>
<type 'str'>
<type 'str'>

# -*- coding: utf-8 -*-
import binascii
c = 'fUT'
e = 0  #暂存结果
for i in c:
  d = ord(i) #单个字符转换成ASCii码
  e = e*256 + d  #将单个字符转换成的ASCii码相连
print("e:%x" %e)
print type(e)

e:665554
<type 'int'>
