Scripting languages are programming languages that don’t require an explicit compilation step. For example, in the normal case, you have to compile a C program before you can run it. But in the normal case, you don’t have to compile a JavaScript program before you run it. So JavaScript is sometimes called a “scripting” language. … Read more
The escape character in batch scripts is ^. But for double-quoted strings, double up the quotes: “string with an embedded “” character”
EDIT: For Python3 (or greater): >>> mydict {‘four’: 4, ‘three’: 3, ‘one’: 1} >>> for k in list(mydict.keys()): … if mydict[k] == 3: … del mydict[k] … >>> mydict {‘four’: 4, ‘one’: 1} The rest of the answers works fine with Python2 but do not work for Python3 and raises RuntimeError. RuntimeError: dictionary changed size … Read more
