至少在py2x中

in 3x

bytes.fromhex(b'7668647866696c654d006900630072006f0073006f00660074002000570069006e0064006f0077007300200036002e0033002e0039003600300030002e003100370033003900360000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000'.decode("ascii"))

扩展Joran的回答，

import string
data = bytes.fromhex(b'7668647866696c654d006900630072006f0073006f00660074002000570069006e0064006f0077007300200036002e0033002e0039003600300030002e003100370033003900360000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000'.decode("ascii"))
print("".join(chr(c) if chr(c) in string.printable else '.' for c in data))

结果：

vhdxfileM.i.c.r.o.s.o.f.t. .W.i.n.d.o.w.s. .6...3...9.6.0.0...1.7.3.9.6.........................................................................................................................................................................................
