Exercise: Your first website Exercise: getting input from the browser Exercise: Create your Web game Select a project, read through its documentation and easy tutorials. During the reading process, write the code in the document yourself and let them operateYes. I learned this way, in fact, every programmer is doing so. After reading the tutorials and documentation, try writing something.Come out. Write anything, even if it is written by others can be, as long as the things can be done. After f

, in which case a sequence of tuples is generated with the elements in the sequence parameter. Here's an example of using the map () function:Def Add_one (a): return a + 1def add_two (A, B): return a + bdef add_three (A, B, c): return a + b + ca = [1, 2, 3, 4, 5]b = [1, 2, 3, 4, 5]c = [1, 2, 3, 4, 5]result = Map (Add_one, a) print Resultresult = Map (Add

As Hillary describes it, the language itself and the community around it have this attitude: "Don't worry, we'll protect you if something goes wron
