In this article, we will learn about the “with” statement in python and its uses. The with statement in Python replaces a try-catch block with a simple shorthand. More significantly, it ensures that resources are closed immediately after processing. Reading or writing to a file is a common use of the with statement. A context manager is a function or class that supports the with statement. A context manager enables you to open and close resources right when you want to. The open() function, for example, is a context manager. When you use the with statement to call the ... Read More
It can be difficult for beginners to grasp the concept of Python modules and libraries. You can tell from the zoom-out content that each of them is a collection of codes. But there is a significant difference between them. In this article, we will show you the major difference between python modules and libraries. Python Modules and Libraries Real-world programs are complicated. Even simple software contains thousands of lines of code. Because of this, writing code in continuous flow is difficult for programmers and developers to grasp. Developers utilize modular programming to facilitate learning and make it logically separated. It ... Read More
Introduction ( what is Sushiswap ? ) Sushiswap is a Decentralized blockchain application also known as DAPP. It is a digital exchange where we can deal with blockchain-based assets or tokens ( Cryptocurrencies ). Decentralized = Non-influenced or controlled by any individual or group A decentralized exchange offers famous services like Trading, Swapping, and Liquidity pools. Decentralization works upon distributed and peer-to-peer network connections and Sushiswap does in the same way. It provides a way to transact between peers and minimizes the transaction fee and leverages the reward to its users in terms of Sushi tokens. Key features Sushiswap ... Read More
A smart contract is nothing but a piece of code (computer program) that uses distributed ledger technology to follow the core principle of blockchain i.e distributed, trustless, and transparency. It is an immutable (Non- changeable) digital file having data and predefined code with an address on the network. That predefined code of conditions defined in the smart contract should be met and verified on specific event occurrences for smooth execution. It follows the logic of If/else and do/while. It is used to automate the execution of programs to save time without using intermediaries. It has various advantages over the conventional ... Read More
The given task is to sort an array of objects by using string property value in JavaScript. Assume there is an array of objects and we need to sort those elements by using the string property. In this below scenario, we are sorting array of objects by "company" property. const array = [ {Company: 'Oneplus', Manufacturing: 'China'}, {Company: 'Samsung', Manufacturing: 'South korea'}, {Company: 'Nothing', Manufacturing: 'India'} ]; Output = // it sorted the array of objects by "company" property. [ {"Company":"Nothing", "Manufacturing":"India"}, {"Company":"Oneplus", "Manufacturing":"China"}, ... Read More
The given task is to replace the elements in an array with elements of another array. Input-Output Scenario Let’s look into some input-output scenarios. Consider there are there two arrays with elements in it. The first array is having more elements than the second array and we are replacing a part of elements in the first array with the elements from second array. Array1 = [1, 3, 5, 7, 2, 4]; Array2 = [3, 6]; Output = [3, 6, 5, 7, 2, 4] // elements got replaced Let’s consider another scenario, where the elements in the first array are ... Read More
Today In the computer industry, testing becomes more inclined to better quality and optimization, without any delay in operation and execution of business requirements. Developing good quality products and services without incorporating higher costs into their production becomes a tedious task. And this becomes more problematic when we are in blockchain technology where everything is linked to crypto transactions even for small amounts of transactions. The testing environment gives us a better solution to pre-production in blockchain development where we can use Test Tokens, also known asTest Faucets for our smart contract deployment. These test Faucets have no value in ... Read More
In this article, the given task is to get the best way of finding the length of a JSON object in JavaScript. Input-Output Scenario Let’s look into this input-output scenario. Consider there is an object with some keys and values in it. we need to get the length of the object. const MyObj = { Name: "Mike", Age: 34 }; document.write(Object.keys(MyObj).length); // Output: 2 Using Object.keys() The Object.keys() method will return the output in form of array of a given object’s own enumerable properties names. It will return the output of keys ... Read More
The given task is to remove the negative values from the array. Input-Output Scenario Let’s look into input output scenarios. Consider there is an array and it is having both negative and positive integer values. We need to remove the negative values from the array and return the array. Input = [-2, 5, -7, 32, 78, -32]; Output = [5, 32, 78] Now let’s assume there are no negatives integer values in the array. so, the array will be returned in the same order. Input = [56, 43, 12, 67, 69, 34]; Output = [56, 43, 12, 67, 69, ... Read More
The given task is to perform joining arrays to form strings in JavaScript. Input-Output Scenario Let’s look into some input-output scenarios. Consider there is an array having some elements in it and we are trying to join that array to form the string. Input = [32, 45, 65, 12, 07, 55]; Output = 32, 45, 65, 12, 07, 55 //String Let’s look into another scenario, where we are having two arrays and we are trying to join those two arrays and form a string. Array1 = [123, 453, 656, 654, 125, 757]; Array2 = ["Hello", "honey", "bunny"]; Output = ... Read More
