Python Hex to Ascii

Question

如何使Python通过文件循环并将十六进制转换为ascii？问题是，当Python通过文件循环时，它看到\n并且不解析该文件。

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 

的错误跟踪：

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 

这里是什么在Test.doc的：

Answer 1

在你的字符串只要使用.strip()，它会删除后\n。

import binascii 

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