如何调用在python终端脚本中使用的文本文件

Question

我用python写了一个二进制解码器，但是我很难把文本文件传给它。你知道吗

"""

Date :28/3/17
File Name:binary_to_string.py

"""

import sys


def binary_to_str(binary_string):
    """
    This function take a binary string as argument and convert to string
    :param binary_string: string in 0 or 1 from
    :return:
    """
    bits = 8  # initialize bit to 8 means by default we are assuming  8 bit binary
    # checking  for backslash if we found first 8 bit give backslash then we reassign  bit to 7
    if ord(chr(int(binary_string[:8], 2))) == 145:
        bits = 7

    result_string = ''
    # iterate all group of 7 or 8 character in binary string based on bits
    # and append to result string
    for i in range(0, len(binary_string), bits):
        result_string += chr(int(binary_string[i:i + bits], 2))
    return result_string


def read_file(file_name):
    """
    This function takes file name as input and read file line by line and
    append to binary_str and return it
    :param file_name: 
    :return: 
    """
    binary_str = ''
    with open(file_name, 'r') as f:
        for line in f:
            binary_str += line.strip()
    return binary_str


if __name__ == '__main__':
    input_file = sys.argv[1]
    print(binary_to_str(read_file(input_file)))

我正试图传入一个带有二进制消息的文本文件：

100100011001011101100110110011011110100000101011111011111110010110110011001000100001

它与二进制文件一起位于pythonpracice文件夹中的文本文件binary1.txt中_字符串.py文件。你知道吗

我从终端收到的错误如下：

bthib@bthib-cyberstorm ~ $ cd pythonpractice

bthib@bthib-cyberstorm ~/pythonpractice $ python ./binary_to_string.py > binary1.txt

/usr/bin/python: can't find '__main__' module in './binary_to_string.py'

Answer 1

错误//bash:./binary\u to_强.py：没有这样的文件或目录： 你在python脚本中给了一个目录来调用吗？你知道吗

可以使用file对象将您想要的二进制值传递给textfile
