Though maybe not interesting to very many, I am posting this insight for two reasons: (1) I feel I owe Chris Wohlert the answer I have found myself (2) more importantly, I’d … Read more
This sets x to a value from -15 to 15 (inclusive) based on the voltage at pin analogPort. 15 means 5 volts and -15 means 0 volts. This value is then used to set a delay between 100 (-(pow(2*15,2))+1000) and 1000 (-(pow(2*0,2))+1000) since the square of 2*x and 2*-x yield the same number. In other … Read more

First of all you need to correct this: d= {‘D’, ‘V’): -5, (…) >> d= {(‘D’, ‘V’): -5, (…) after doing it you just need to call it as: return d[(‘S’, ‘X’)] or print d[(‘S’, ‘X’)] This should work. Otherwise just let us know 1 solved how do i get a value from a dictionnary … Read more

In this case, the key is a tuple of two elements (‘B’, ‘A’) and the value is the one you are trying … Read more
As noted in the comments: you should actually move/rename the folder, not just print out its name. DirectoryInfo dir = new DirectoryInfo(“C:/Users/Wiz/Desktop/folder/”); foreach (var item in dir.GetDirectories()) { item.MoveTo(Path.Combine(item.Parent.FullName, “a” + item.Name)); Console.WriteLine(“a” + item.Name); } Console.ReadLine(); 1 solved How add letter for the folders start
