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 base64import hmacimport hashlibimport urllibimport urlparseimport jsonimport urllibimport sysdef _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 rif __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
