如何在python中将"ASCII"转换为"HEX"

我有一个文件需要阅读.但使用下面的代码它只能显示ASCII

with open('Hello.DAT','rb') as f:
    data= f.read()  
    print(data)

它可以以这种格式打印数据:

01201602180000020000000007000000000054000000000000\X0

如何将此数据转换为HEX值,如下所示:

30 31 32 30 31 36 30 32 31 38 30 30 30 30 30 32 30 30 30 30 30 30 30 30 37 30 30 30 30 30 30 30 30 30 30 35 34 30 30 30 30 30 30 30 30 30 30 30 30 5c 78 30

Answer 1

假设python3:

with open('Hello.DAT','rb') as f:
    data = f.read()  
    print(" ".join("{:02x}".format(c) for c in data))

(在python2中更改format(c)为format(ord(c)))
