A hash collection is a data structure that contains key-value pairs in Go and enables quick lookups, additions, and deletions. The value that corresponds to the key can be accessed by hashing the key into an index. Hash collections in the form of maps have built-in support in Go. Here, a map is a reference type that is declared by using the map keyword, followed by the key type and value type in the format. In tis example, we will use two methods to get keys from a hash collection, in the first example we will use append method to ... Read More

In golang, we can use hashmap to perform various operations like deleting, updating, and storing the values in the hash collection. In this article, we are going to understand get key based on a value from the hash collection using two different examples. In the first example, we will use an external function and iterate the map to get the key from the value, in the second example we will use a reverse map to get the key from the desired value. Algorithm Create a package main and declare fmt(format package) in the program where main produces executable codes ... Read More

In Golang, we can use a simple indexing method and slicing method to add items to the hash collections. A hash function is used for retrieving and storing the data. In this article are going to see two different examples where we are going to use the above-mentioned methods to add items to a hash collection in go programming language. Syntax func make ([] type, size, capacity) The make function in go language is used to create an array/map it accepts the type of variable to be created, its size and capacity as arguments. Algorithm Import the required ... Read More

Introduction Subplot creation is one of several tools for data visualization provided by the Python library Plotly. A big narrative can be broken up into multiple smaller ones using subplots. Sometimes, in order to give the main story greater depth and consistency, it may be essential to give each subplot its own title. Syntax Customizing subplot titles in plot grids is made possible through the usage of the subplot_titles parameter, which enables us to create unique titles for each plot. The make_subplots() function is essentially a factory method that allows us to establish a plot grid with a designated number ... Read More

IntroductionBefore Google acquired Youtube, most of it was built using PHP. However, PHP at that time had a lot of restrictions for cross-platform applications, and generated a lot of clutter.  After Google’s intervention, Youtube underwent an overhaul, with a major change in interface and security. In this article, we will go through the portions of Youtube where Python is used as the primary language. Reasons why Python is Used Reducing clutter Implementing newer features Frontend and API deployment Increased security Data visualization and analysis Easier maintenance Reason 1: Reducing ClutterAs Youtube was first established ...

The coolest Python program I have ever made is Python password hasher. Let's first understand what python password hashing is. What is Password Hashing? Python Password hashing is a form of advanced encryption which can be used to store passwords online safely. In today’s world of everything being online, user passwords are one of the most easily attacked sensitive information on the internet. The password string is converted to a string of random characters using different hashing algorithms, which have been used in my program. The user is instructed to input the password string, then select the appropriate hashing algorithm ... Read More

What is a Dictionary in Python? A dictionary is Python’s own indigenous representation of a data structure, and can be considered similar to maps in C++. It is a dynamic data structure which stores key-value pairs dynamically, and is mutable. It can be better understood as an associative array, where each element is associated with its key value. Can one key hold more than one value? Although dictionaries in Python store values as key-value pairs, it is possible to store more than one value corresponding to the same key in a dictionary. This is performed by setting containers like ... Read More
