 | Consider this example: def ls(): l = [1,2,3,4,5] for i in range(len(l)): print l[-(i+1):], Now try to figure out how to combine those lists and apply what **woooee** said to get your desired result.  |

 | You could use a class to store all your employees information. Than, just add to your list those objects. Here's a small example: class Employee: def __init__(self, name, salary, desc): self.name = name self.salary = salary self.desc = desc def __str__(self): return 'Name: '+self.name+', Salary: '+str(self.salary)+', Description: '+self.desc def run(): … |
| | If using one-line examples, here, this might help you: lst, l = [('Meat', 'Milk'), ('Cake - Cookie'), ('Apple', 'Orange')], [] [l.append(tuple(i.split(' - '))) if '-' in i else l.append(i) for i in lst] print l Should produce this output: ''' [('Meat', 'Milk'), ('Cake', 'Cookie'), ('Apple', 'Orange')] ''' |
| | Beside the utterly ugly format you have presented us in this code, where's the problem in converting c++ to c? Post your conversion so far (of this code), so that we know you'd tried (and failed).  |
 | What can I say, for your wine experience to be legendary, you always have to be accompanied by a bear. You'll probably want to give him just a beer, sice wine affects them greatly.  |
 | Make a class which is recognized as an item, either a food item or a data item, or whatever. Read the first file (which is your database of products), and fill in the class' elements (which will be like this: id, name, type, price). To get the bill, read the … |

| | Make use of what Java already offers you: [Click Here](http://goo.gl/9F7iK) You can use the method `Integer.parseInt(string containing the number in some base, base)` method, but pay attention as digits from the string must be included in the radix of the 2nd argument. For example, if you want to parse the … |
| | Re: toggle button You can. As **JamesCherrill** said, you'll need to add a functionality to each of your GUI components, so that it would handle the "events" generated by the user. Here's a small example. We have a button named `"Click me"`, which can be pressed. Near him there's a label named `"Clicks: … |
| | You could also use the [stringstream](http://www.cplusplus.com/reference/sstream/stringstream/) class from C++. Here's a little example: #include <iostream> #include <string> #include <sstream> #define SIZE 10 using namespace std; bool isInt(string s){ //checks if what the user inserted is an INTeger if (s=="" || s==" " || s == ".") return (false); string dash="-"; …  |

| | Indeed, deleting from a memory-contiguous-like container (such as a vector, or an array), requires a bit of time, because the system has to shift all the elements to get the desired result, but, it has some advantages. I see you mention a lot that you want to access the quesitons … |

| | Re: dangling pointer delete obj; obj=obj2.create(); obj->show(); delete obj; This is legal. Even though you deleted the obj (freed that memory), the pointer is overwritten by the next line `obj = obj2.create();`. So by calling `obj->show();` after that, it would perfectly display `"Derived2"`, since obj points to a new Object of type Derived2. |
