代码

    string progToRun = "test.py";
    char[] spliter = { ‘\r‘ };

    Process proc = new Process();
    proc.StartInfo.FileName = "python.exe";
    proc.StartInfo.RedirectStandardOutput = true;
    proc.StartInfo.UseShellExecute = false;
            
    string psw = "123456";
    string parameters2 = "haha";
    //文件路径+参数集合
    proc.StartInfo.Arguments = string.Concat(progToRun, " ", psw.ToString()," ", parameters2.ToString());
    proc.Start();

    StreamReader sReader = proc.StandardOutput;
    string[] output = sReader.ReadToEnd().Split(spliter);

    foreach (string s in output)
        Console.WriteLine(s);

    proc.WaitForExit();

    //取出计算结果
    Console.WriteLine(output[0]);

    Console.Read();

import base64
import hmac
import hashlib
import urllib
import urlparse
import json
import urllib
import sys

def _auth_data():
    psw=sys.argv[1]
    parameters2=sys.argv[2]
    md5 = hashlib.md5()
    md5.update(psw.encode(‘utf-8‘))
    md5.update(‘hello‘.encode(‘utf-8‘))
    s = json.dumps({"assetPwd": md5.hexdigest()})
    r=urllib.quote(s, safe=‘‘)
    print r
    return r

if __name__ == ‘__main__‘:
    _auth_data()

需要注意的是：
（1）示例的python版本是2.7，可以用python3，这个和你的环境有关
学习过程中遇到的比较揪心的问题也是“python2找不到python3的库、方法”之类的问题，保证环境一致并且正确啊╮(╯_╰)╭
（2）python基本语法问题，缩进要么是空格，要么是tab，保持一致，否则VS会报错
