...ition, but if you have a more complex function that you needed to apply to all the elements then map may be a good fit. In your example it would be: >>> map(lambda x:x+1, [1,2,3]) [2,3,4] share | ...

...ring. When there is more than one component to the argument then they must all be strings so that string concatenation can be applied. The preprocessor can never assume that an unquoted string should be treated as if it were quoted. If it did then: #define ABC 123 int n = ABC; would not compile. ...

... have the same results. Pre-increment is a little bit faster because it really increments the variable and after that 'returns' the result. Post-increment creates a special variable, copies there the value of the first variable and only after the first variable is used, replaces its value with seco...

...sizeof(struct { int: -!!(e); })) (e): Compute expression e. !!(e): Logically negate twice: 0 if e == 0; otherwise 1. -!!(e): Numerically negate the expression from step 2: 0 if it was 0; otherwise -1. struct{int: -!!(0);} --> struct{int: 0;}: If it was zero, then we declare a struct with an an...

I tend to declare as static all the methods in a class when that class doesn't require to keep track of internal states. For example, if I need to transform A into B and don't rely on some internal state C that may vary, I create a static transform. If there is an internal state C that I want to be ...

... that every reference type gets this extra state in its space that is typically undesired. A string variable could be any sequence of characters, or it could be this crazy extra null value that doesn't map into my problem domain. A Triangle object has three Points, which themselves have X and Y va...

...t to to do it beforehand, if you just add the line to the .gitignore file, all previously committed .pyc files will still be tracked, so you'll need to remove them from the repository.
