The same works for tuples: And strings, which are really just arrays of characters: It was intentionally done this way so that lists, tuples and other container types or iterables didn’t all need to explicitly implement a public .length() method, instead you can just check the len() of anything that implements the ‘magic’ __len__() method. Sure, this may seem redundant, but length checking … Read more
You are trying to call do_something before you declare it. You need to add a function prototype before your printf line: Or you need to move the function definition above the printf line. You can’t use a function before it is declared.
TL;DR You want this: Mappings The YAML equivalent of a JSON object is a mapping, which looks like these: Note that the first characters of the keys in a block mapping must be in the same column. To demonstrate: Sequences The equivalent of a JSON array in YAML is a sequence, which looks like either … Read more
If it’s a one-dimensional array a, will give the number of elements of a. If b is a rectangular multi-dimensional array (for example, int[,] b = new int[3, 5];) will give the number of dimensions (2) and will get the length of any given dimension (0-based indexing for the dimensions – so b.GetLength(0) is 3 and b.GetLength(1) is 5). See System.Array documentation for more info. As … Read more
It’s easier to store data of different sizes in a linked list. An array assumes every element is exactly the same size. As you mentioned, it’s easier for a linked list to grow organically. An array’s size needs to be known ahead of time, or re-created when it needs to grow. Shuffling a linked list … Read more
I’m trying to read a CSV file into a list of lists (of strings), pass it around for getting some data from a database, build a new list of lists of new data, then pass that list of lists so it can be written to a new CSV file. I’ve looked all over, and I can’t … Read more
There are several ways of checking if an variable is an array or not. The best solution is the one you have chosen. This is the fastest method on Chrome, and most likely all other browsers. All arrays are objects, so checking the constructor property is a fast process for JavaScript engines. If you are … Read more
This works Output:
Depending on the encoding you wish to use:
Note that the characters in $IFS are treated individually as separators so that in this case fields may be separated by either a comma or a space rather than the sequence of the two characters. Interestingly though, empty fields aren’t created when comma-space appears in the input because the space is treated specially. To access an individual element: To … Read more
