如何在python中将十进制0打印为000

Question

我正在将十六进制数据转换为十进制,范围从00到FF

 hex_data = "FF"
int("0x" + hex_data , 16) 

返回255,但是当我将0作为hexdata时,它给出0 wheras我需要它作为000

怎么做

Answer 1

你需要格式化它:

hex_data = "FF"
number = int("0x" + hex_data, 16) 
print '%03d' % number # either this
print '{:03d}'.format(number) # or this (Python >= 2.6)
