python3 is not Python syntax, it is the Python binary itself, the thing you run to get to the interactive interpreter. You are confusing the command line with the Python prompt. Open a console (Windows) or terminal (Linux, Mac), the same place you’d use dir or ls to explore your filesystem from the command line. … Read more

Use eval: x=”ls | wc” eval “$x” y=$(eval “$x”) echo “$y”
this is all you have to do run shell commands from C# string strCmdText; strCmdText= “/C copy /b Image1.jpg + Archive.rar Image2.jpg”; System.Diagnostics.Process.Start(“CMD.exe”,strCmdText); EDIT: This is to hide the cmd window. System.Diagnostics.Process process = new System.Diagnostics.Process(); System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo(); startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden; startInfo.FileName = “cmd.exe”; startInfo.Arguments = “/C copy /b Image1.jpg + Archive.rar … Read more

In JavaScript your data would look like this. var someVariable = { “server”:{ “snapMaxFileSizeKB”: 1024, “upldr”: [“upldr1”, “upldr3”, “upldr5”, “upldrg1”, “upldrg5”, “cluster”], “localhost”: false }, “app”: “dtube/0.7”, “beneficiary”: “dtube”, “dmca”: true, “pageTitleSeparator”: “-“, “appName”: “DTube”, “ipfs”: … Read more
This isn’t working because you’re using globals. When you hit if tape[selectedCell] == int(”.join(num)): for the third if statement, nums contains [‘1’, ‘1’] because both if statements have added a 1 to num, so when you do int(”.join(num)) you end up with 11 which is not equal to 1. You need to refactor this code … Read more
