Sometimes we need to fetch and print the value of a TensorFlow variable to guarantee our program is correct. For example, if we have the following program: import tensorflow as tf import numpy as np a = tf.Variable(tf.random_normal([2,3])) # declare a tensorflow variable b = tf.random_normal([2...

In order to print the value of a variable such as, set tempVar "This is a string." The argument in the puts statement is preceded by a $ sign, which tells Tcl to use the value of the variable. % set tempVar "This is a string." This is a string. % puts $tempVar This is a s...

// Default export export default {}; // Named export export const SomeVariable = {};

Javascript engines first look for variables within the local scope before extending their search to larger scopes. If the variable is an indexed value in an array, or an attribute in an associative array, it will first look for the parent array before it finds the contents. This has implications wh...

The diamond problem, or multiple inheritance, is handled by Scala using Traits, which are similar to Java interfaces. Traits are more flexible than interfaces and can include implemented methods. This makes traits similar to mixins in other languages. Scala does not support inheritance from multipl...

Functions allow you to specify these types of parameters: positional, named, variable positional, Keyword args (kwargs). Here is a clear and concise use of each type. def unpacking(a, b, c=45, d=60, *args, **kwargs): print(a, b, c, d, args, kwargs) >>> unpacking(1, 2) 1 2 45 60 ()...

One of the most powerful capabilities in Excel is the use of Pivot Tables to sort and analyze data. Using VBA to create and manipulate the Pivots is easier if you understand the relationship of Pivot Tables to Pivot Caches and how to reference and use the different parts of the Tables. At its most ...

These excellent reference sources provide descriptions and illustrations of the various ranges in Pivot Tables. References Referencing Pivot Table Ranges in VBA - from Jon Peltier's Tech Blog Referencing an Excel Pivot Table Range using VBA - from globaliconnect Excel VBA

Two important things to note when adding fields to a Pivot Table are Orientation and Position. Sometimes a developer may assume where a field is placed, so it's always clearer to explicitly define these parameters. These actions only affect the given Pivot Table, not the Pivot Cache. Dim thisPivot ...

This example changes/sets several formats in the data range area (DataBodyRange) of the given Pivot Table. All formattable parameters in a standard Range are available. Formatting the data only affects the Pivot Table itself, not the Pivot Cache. NOTE: the property is named TableStyle2 because the ...

An actor inside Service Fabric is defined by a standard .NET interface/class pair: public interface IMyActor : IActor { Task<string> HelloWorld(); } internal class MyActor : Actor, IMyActor { public Task<string> HelloWorld() { return Task.FromResult(&quot...

You may have noticed that many applications have double-back-click functionality to exit the app. In this example, we are overriding the default back button action using the onBackPressed() method override. This method will Toast a message for the single back-click action, and will close the app if...

The var keyword allows a programmer to implicitly type a variable at compile time. var declarations have the same type as explicitly declared variables. var squaredNumber = 10 * 10; var squaredNumberDouble = 10.0 * 10.0; var builder = new StringBuilder(); var anonymousObject = new { One =...
