Question

我正在尝试从Linux环境中解析某些内容，并使用python将它们转储到Windows环境中的excel文件中。

eg: foo/bar/myfile.txt在Windows env C:foo\bar\myfile.txt中有一些我想粘贴到excel文件的内容

我知道如何提取所需的信息，但找不到从python的Linux env在Windows操作系统中创建文件的解决方案。任何小信息都会有所帮助。谢谢！

import csv
import sys
import subprocess


def env_key_values(host):
    """
    The subprocess.Popen will execute the env command on the remote
    Linux server then return the results.
    """
    ssh = subprocess.Popen(["ssh", host, "env"],
                            shell=False,
                            stdout=subprocess.PIPE,
                            stderr=subprocess.PIPE)
    """
    Read each line from stdout selecting only the varname=value lines.
    Split the line on the '=' character. Use the first element as the

    yield the result.
    """
    for line in ssh.stdout:
        str_line = line[:-1].decode("utf-8")
        if "=" in str_line:
            key_values = str_line.split("=")
            values = "=".join(key_values[1:])
            yield (key_values[0], values)
