Run python Script(having input()) exe form C#

I have python script having input command i.e taking input(directory) from user. Using PyInstaller I have generated exe of that script. Now I want to consume this exe from C# by giving input parameter. But Somehow even after giving arguments from C# it is not taking and pops up Python exe command prompt.

Python Code:

def CreateCSVFile(CSVDirectory):
    try:
        file_path = os.path.join(CSVDirectory, 'ExportResult_Stamp.csv')
        ## delete only if file exists ##
        if os.path.exists(file_path):
            os.remove(file_path)
        # Create column names as required
        row = ['FileName', 'Document123','abc','xyz','zzz']
        with open(file_path, 'w+') as csvFile:
            writer = csv.writer(csvFile)
            writer.writerow(row)
        csvFile.close()
    except Exception as e:
        print(str("Exception occurs:"+ e))

strDocDir = input("Give document directory:")
#print(strDocDir)
if os.path.exists(os.path.dirname(strDocDir)):
    CreateCSVFile(strDocDir)
else:   
    warnings.warn("Provided directory doesn't exist:" + strDocDir)

C# Code:

string strCurrentPath = System.IO.Path.GetDirectoryName(Application.ExecutablePath);
                ProcessStartInfo startInfo = new ProcessStartInfo(string.Concat(strCurrentPath, "\\Test\\", "CSV.exe"));
                startInfo.Arguments = @"C:\Pankaj\Office\ML\Projects\Stampdocuments\DDR041";
                startInfo.UseShellExecute = true;                
                var process = System.Diagnostics.Process.Start(startInfo);
                process.WaitForExit();

Please suggest.
