菜农Python菜鸟学习笔记之两种16进制转换函数的构建

#! -*- coding:utf-8 -*-
def int2hex(v, size):#%无法嵌套
    return (("%0" + str(size) + "X") % v)[-size:]
def inttohex(v, size):#{}可以嵌套
    return "{:>0{}X}".format(v,size)[-size:]
def hextoint(s):
    return int(s, 16)

i=0x0123456789aBcdeF
j=0x12Ab
s="fFFf"
print(int2hex(i, 5))
print(int2hex(j, 6))
print(inttohex(i, 5))
print(inttohex(j, 6))
print(inttohex(1234, 4))
print(inttohex(0x1234, 4))

运行结果：
BCDEF
0012AB
BCDEF
0012AB
04D2
1234
