String are identified as a contiguous set of characters represented in the quotation marks. Python allows for either pairs of single or double quotes. Strings are immutable sequence data type, i.e each time one makes any changes to a string, completely new string object is created. a_str = 'Hello ...
In the following, weight is declared as a mutable field. type person = { name: string; mutable weight: int };; Remark: As far as design is concerned here, one would consider the fact that a person's name isn't likely to change, but their weight is.
Initializing a record with mutable fields isn't different from a regular record initialization. let john = { name = "John"; weight = 115 };;
To assign a new value to a mutable record field, use the <- operator. john.weight <- 120;; Note: The previous expression has a unit type.
Generally tf.gather gives you access to elements in the first dimension of a tensor (e.g. rows 1, 3 and 7 in a 2-dimensional Tensor). If you need access to any other dimension than the first one, or if you don't need the whole slice, but e.g. only the 5th entry in the 1st, 3rd and 7th row, you are b...
Starting with version 2.7 ElementTree has a better support for XPath queries. XPath is a syntax to enable you to navigate through an xml like SQL is used to search through a database. Both find and findall functions support XPath. The xml below will be used for this example <Catalog> &l...
A simple way to catch unhandled errors (exceptions) in a VFP application is to use the ON ERROR command near the beginning of your main program. The following ON ERROR command calls a method in the current program called "errorHandler". The values returned by ERROR (the VFP Error Number),...
While the JCE secures cryptographic operations and key generation, it is up to the developer to actually manage their keys. More information needs to be provided here. One commonly-accepted best practice for handling keys at runtime is to store them only as byte arrays, and never as strings. This i...
More information needed. A cryptographic hash function is a member of a class of functions with three vital properties; consistency, uniqueness, and irreversibility. Consistency: Given the same data, a hash function will always return the same value. That is, if X = Y, f(x) will always equal f(y) ...
navigator.mediaDevices is the common method adapted in Chrome and FF to getUserMedia as of now. A promised based call back which returns local stream on success navigator.mediaDevices.getUserMedia({ audio: true, video: true }) .then(stream => { // attach this stream to window obje...
GTKWave is a fully feature graphical viewing package that supports several graphical data storage standards, but it also happens to support VCD, which is the format that vvp will output. So, to pick up GTKWave, you have a couple options Goto http://gtkwave.sourceforge.net/gtkwave.zip and downloa...
This example uses Icarus and GTKWave. Installation instructions for those tools on OSx are provided elsewhere on this page. Lets begin with the module design. This module is a BCD to 7 segment display. I have coded the design in an obtuse way simply to give us something that is easily broken and...
You should create functions in a controller like insert, update, delete, and clear cart etc. eg : for insert new item in cart write below code that accepts value. $cartItem = array( 'id' => 'MOTOG5', 'qty' => 5, 'price' => 100.99, 'name' => 'Motorola Moto G5 - 16 GB',...
This example is based on this post: TensorFlow - numpy-like tensor indexing. In Numpy you can use arrays to index into an array. E.g. in order to select the elements at (1, 2) and (3, 2) in a 2-dimensional array, you can do this: # data is [[0, 1, 2, 3, 4, 5], # [6, 7, 8, 9, 10, 11], # ...
Open your jenkins instance script console http://yourJenkins:port/script following is an example for how to get information about this instance. copy the code to the console and click "Run". /* This scripts shows how to get basic information about Jenkins instance */ def jenkins = Jenki...
Grab installer from http://scons.org/pages/download.html Or try pip installation tool that comes with Python: pip install scons If scons still can't be found after that, make sure that Python Scripts/ folder is added to PATH for your Python installation.

IServiceCollection To start building an IOC container with Microsoft's DI nuget package you start with creating an IServiceCollection. You can use the already provided Collection: ServiceCollection: var services = new ServiceCollection(); This IServiceCollection is nothing more than an implemen...
