Python - 从文件中将八进制转换为非英语文本

Question

I am trying to convert Non-English file encoded in Octal back into it's native format and store it in another file. The files include:

• i_file : The input Original File with Octal Encoded text
• o_file : The output Target File which should contain the Kannada(The non-English Language in question) text.
• octal_to_text.py : The python program that should take the octal text in in the input file and generate corrusponding non-English text in the target file.

Sample i_file

The code i thought would work would be to convert the text into a byte array using bytearray() , then decode it to utf-8 and write it to the targe file. octal_to_text.py

"""
Convert file contents from Octal to text

"""

with open('i_file','r') as tl, open('o_file','w+') as tk:
    for line in tl.readlines():
        line = (line.strip())
        br = bytearray(line)
        tk.write("{}\n".format(br.decode('utf-8')))

In the code above however, the output file generated is the same as the input. bytearray doesn't seem to be doing anything. What exactly am I doing wrong here? Could you provide a python2.7 solution?

NOTE The output file should contain characters like the ones shown below

Answer 1

The print statement for an Octal encoded string, decodes Octal to the non-English notation only when working the python interpreter.

Thus, a simple work around is to perform the following steps:

1. Copy the contents of the file to be decoded
2. Open the python interpreter and assign the file contents to a variable in a multi line string.
3. Print the variable
4. Copy contents to a new file
