In the Go programming language, strings are a built-in data type that represents sequences of characters. They are defined using double quotes (") and can contain any valid Unicode characters. A substring is a portion of a string that contains a sequence of characters from the original string. A substring can be obtained in Go by using the slicing syntax on a string value. In this article we are going to learn different methods to get the index of a substring in a string using golang programming. Method 1: Using a For Loop In this method, the function that we ...

In this article, we will be discussing how to remove duplicate elements from a dictionary in Python. A dictionary is a data structure that stores key-value pairs, and it is an essential data type to understand when learning Python. However, there may be cases where we have a dictionary with duplicate elements, and we want to remove them to clean up the data. We can declare a dictionary in the following way − thisdict = { "brand": "Ford" , "model": "Mustang" , "year": 1964 } However, a dictionary can contain duplicate value for different keys, but we might ...

In Python, tuples are a useful data type for storing a collection of items. Sometimes, it may be necessary to print the keys and values of a tuple in order to understand or debug your code. In this article, we will be discussing, how to print the keys and values of a tuple in Python. We will go over the syntax for accessing these elements and will provide examples of how to do so. First, we will learn about what is tuple and what we mean by the keys and values of the tuple. What does a Python tuple mean? ... Read More

In Python, tuples are an important data type for storing a collection of items. Sometimes, it may be necessary to print the elements of a tuple in order to understand or debug your code. In this article, we will be discussing how to print the elements of a tuple in Python. We will go over the syntax for accessing and printing tuple elements and will provide examples of how to do so. We can define a tuple in the following way − tup1 = ("this" , "is" , “a” , "tuple") tup2 = (1, 2, 3, 4, 5 ); tup3 ... Read More

Tuples are an important data type in Python and are often used to store a fixed set of elements. In this article, we will be discussing how to extract the first and last elements from a tuple in Python. We will go over the syntax for accessing these elements and will provide examples of how to do so. What is a Tuple in Python? Tuples allow for the storage of several things in a single variable. One of python’s four built-in data types for storing data collections is the tuple. Unchangeable and ordered collections are called tuples. Round brackets are ... Read More

In Python, a tuple is an immutable sequence type that is commonly used to store a collection of items. A python tuple is very similar to a list in python in terms of nesting, indexing and repetition but one difference is that a tuple is immutable whereas the list is mutable which means we can change the elements of a list but we cannot do the same with a tuple. One other difference is that list uses the square bracket [] for declaration but tuples use simple bracket (). In this article, we will be discussing how to create a ... Read More

Dictionaries are a powerful data type in Python that allow you to store data as key-value pairs. In this article, we will be discussing how to compare elements in two dictionaries in Python. We will go over the syntax for comparing dictionary elements and will provide examples of how to do so. Dictionaries in Python In Python, a dictionary can be created by placing a sequence of elements within curly { } brackets , separated by ‘comma’ ( , ). Dictionary holds pairs of values, one being the key and the other corresponding pair element being its value. Values ... Read More

A server-side scripting language that is frequently used for web development is called PHP (Hypertext Preprocessor). The server runs PHP code, which produces HTML, CSS, and JavaScript, which are then transmitted to the client's browser for rendering. Before the HTML is transmitted to the client's browser, PHP code is embedded in it and executed on the server. To add more values to an array on a button click using PHP, you can use a form with a button that, when clicked, sends a request to a PHP script that adds the new value to the array. Approaches When using PHP, ... Read More

An array in go language is defined as the data structure that is used to store elements in contiguous memory locations. Arrays allow us to search and store elements at constant time. arrays use index to store elements which starts from 0 and goes to n – 1, where n is the length of the array. Here we will use two methods in the first method we will implement the logic in the main section of the program while in the second one we will use an external function. Method 1:Using For Loops In The Main Here we will use ... Read More

In go language a long type variable is not a separate data type but it is an extension made from the integer data type to store even larger types of integers. The main difference between an int data type and long data type is that int data type is 32 bits whereas long data type is 64 bits. Syntax func typeOf (x interface{}) The typeOf() function is used to get the type of any variable. This function is present in reflect package and it takes the variable whose type is to be determined as an argument. The function then ... Read More
