Python Hex到Ascii

Question

如何让Python循环遍历文件并将十六进制转换为ascii？问题是，当Python循环遍历文件时，它会看到\n并且不解析文件。

import binascii

fo = open('test.doc', 'r')

print fo.readlines()

dataFormatHex = binascii.a2b_hex ("%s" %fo)

output = ""
for char in dataFormatHex:
    if char in string.printable: output += char
    else: output += "."
print "\n" + output

错误跟踪是：

Traceback (most recent call last):
  File "C:\Python27\hex2ascii-looper.py", line 7, in <module>
    dataFormatHex = binascii.a2b_hex ("%s" %fo)
TypeError: Non-hexadecimal digit found

以下是test.doc中的内容：

Answer 1

只需在字符串上使用.strip()，就会删除尾随的\n。

import binascii

f = open(yourFile)
for line in f.readlines():
    print(binascii.a2b_hex("%s" % (line.strip()))
f.close()
