Adding two numbers in Python is one of the most basic tasks, where we need to combine their values to get a total. In this article, we will see different ways to add two numbers in Python. Using Arithmetic Operator To add two numerical values in Python, we can use the addition operation, represented by the "+" symbol. It is one of the arithmetic operators in Python that performs the addition operation. Example Here is the basic example that adds the two numbers using the addition operator (+). # Assign values to the variables a = 7 b = ...
Transferring files from one server to another is a most common task in system administration, DevOps and development workflows. The tools such as scp and rsync are used for the file transfer. Python provides different methods and tools to transfer the files from one server to another using a third party libraries such as paramiko and SCPClient. Using Paramiko and SCP for Secure Transfers When we want to copy files securely from one server to another using Python, we can use the libraries Paramiko and SCPClient together. Paramiko is a Python library that helps to implement SSHv2 protocol. This is ...
In Python, a string is one of the data structures that is a sequence of characters enclosed within single quotes '' or double quotes "". It is immutable, i.e., once a string is created, it cannot be changed. When we want to check if both halves of the string have the same set of characters in Python, we can follow the steps below - First, based on the length of the string, we have to split the string into two halves. Next, convert each half into a set of characters using set() function. Finally, compare the two sets using ...
In this tutorial, we are going to build a basic calculator in Python. As we all know that a calculator will give six options to the user from which they select one option and we will perform the respective operation. Following are the arithmetic operations that we can perform using a basic calculator - Addition Subtraction Multiplication Division Floor Division Modulo Steps in Developing the Basic Calculator Following are the steps involved in creating a basic calculator in Python - Defining Arithmetic Functions First, we are defining all the arithmetic operations that can be performed by using a ...
In Python, a string is one of the data structures that is a sequence of characters enclosed within single quotes '' or double quotes "". It is immutable, i.e., once a string is created, it cannot be changed. When we want to generate two output strings based on character occurrence in Python, we have to follow the steps below - First, we need to initialize a dictionary or use the collections.Counter class to count the frequency of each character in the input string. Next, we have to go through the input ...
In Python, we may go through the matrices that are sorted in a particular order. A common case is a matrix where each row and each column is sorted in increasing order, and this does not mean that the entire matrix is sorted. In such cases, we need to extract all elements and print them in a fully sorted order. Row and Column-wise Sorted Matrix? A row and column-wise sorted matrix means each row is sorted from left to right, and each column is sorted from top to bottom. For example, let's consider the following matrix - matrix = ...
When we want to transfer files from our local system to a remote server securely, Python provides possible ways to do the file transfer using the Paramiko and SCP libraries. These libraries support SSH-based file transfer, which is secure and reliable. Installing Required Libraries Before we start with file transfer, we need to install all the required libraries with the help of below commands - pip install paramiko scp Using paramiko and SCP/SSH Paramiko is a third-party library available in Python, which is used to transfer a file to a remote server without using an external SCP module. This ...
When we want to remotely access and execute commands on another machine then we use the paramiko library in Python. Paramiko is a third-party library that is used to connect and communicate securely with remote machines using the SSH, i.e., Secure Shell protocol. It allows us to execute commands, transfer files, and perform other remote tasks programmatically. To use the Paramiko library, first we need to install it in our local system using the below command - pip install paramiko Example Following is the example, in which we connect to a remote server via SSH and perform multiple shell ...
In Python, Dictionaries are used to store structured data. When we want to print this data in a human-readable format or transfer it through the internet, such as to an API, then we need to convert the dictionary to JSON, i.e., JavaScript Object Notation. Python has a built-in module named json to handle such conversions. JSON is JavaScript Object Notation which is a lightweight text-based open standard designed for human-readable data interchange. The JSON format was specified by Douglas Crockford. It has been extended from the JavaScript scripting language. A dictionary in Python is a mutable and unordered collection ...
In Python, a dictionary is a collection of key-value pairs that is used for data retrieval. In some cases, we may need to combine two or more dictionaries into one. This is known as merging dictionaries. In this article, we will explore different methods to merge multiple dictionaries in Python. Using "|" Merge Operator The "|" merge operator in Python is used to merge multiple dictionaries into one and returns the combined dictionary as a new dictionary. If both dictionaries have the same key, then the value from the dictionary on the right side of the operator will ...
