In Python, we can create a string object using Python's inbuilt function str() and also by assigning a sequence of characters to a variable. The sequence of characters is enclosed in the single quote or double quotes. We can also create a multiline string object using triple quotes. In this article, we look at the various ways in which we can create a string object in Python. Example 1:Creating a string object using single quote We can create a string object by simply assigning a sequence of characters enclosed in a single quote to a variable. my_string = 'Hello World!' ...

In python we can use the comparison operators like “==”, ”!=”, “”, ”=” and python inbuilt function like lower() and upper() methods to compare two strings by ignoring case. Strings are character sequences enclosed in double quotes. These operators compare strings based on the Unicode code points assigned to each character of the string. In this article, we will understand how we can compare two strings by ignoring cases of the string. Comparing Strings Ignoring Case To compare two strings in Python while ignoring the case, we can use the lower() or upper() function which converts the string to ... Read More

In Python, we can clear the string buffer by assigning an empty string to the buffer and using Python's inbuilt reset() method. A string buffer is a mutable sequence of characters. These characters can be modified according to the requirements. The string buffer can be modified or cleared before the string is written to an output stream. In this article, we will understand how to clear the string buffer using examples. Method 1 : Assign Empty String to the Buffer One of the methods to clear the string buffer is to assign the buffer with an empty string. Assigning an ... Read More

In Python, we can use inbuilt functions like len() and logic to check the sequence of the characters in the resultant string to know if a string is a valid shuffle of two distinct strings. A valid shuffle of two distinct strings means that a string is formed by mixing the characters of two distinct strings while maintaining the order of the characters of the two original strings. Python provides various inbuilt functions to play with strings. In this article, we will check if the string formed by shuffling the characters of two distinct strings is a valid string or ...

In swift, Binary search algorithm is used to search element from the sorted array. It repeatedly divides the search interval into half and then search the specified element. In the binary search algorithm, the input array must be in sorted order to reduce the time complexity. Algorithm Step 1 − Create a function to implement a binary search algorithm. Step 2 − Inside the function, first we find the lower bound and upper bound range of the given array. Step 3 − Run a while loop till LBound

Matplotlib in Python has various functions like read_csv, sort_values, group_by, etc to perform sales data analysis. Every online business which is involved in product sales of any type uses product sales data analysis to increase their sales and know their customers better. Any company which is involved in any type of e-commerce business uses its sales and customer data to identify trends, patterns, and insights that can be used to improve sales and revenue. The sales data can be used to determine which product has the highest traction, which festive season has the highest demand, and many other trends which ... Read More

Pytorch is an open-source machine learning framework that is widely used to create machine learning models and provides various functions to create neural networks. The activation function is a key component of neural networks. The activation function determines the output of a node in the neural network given an input or set of inputs to the node. The activation function introduces non-linearity in the output of a node of the neural network which is necessary for solving complex machine-learning problems. What is an Activation Function ? Neural networks in artificial intelligence consist of an input layer, a hidden layer, and ... Read More

Action chains in selenium python are the execution of multiple browser actions together in sequence. Selenium is a popular open-source automation testing tool used to test web applications and automate browser actions. Selenium can chain multiple browser actions together and this chaining of multiple actions is known as Action chains. In this article, we will discuss what action chains are in selenium python and how to use action chains to automate our web testing. What are Action Chains in Selenium Python? Action chains are a sequence of actions that are performed in a specific order on a web page to ... Read More

Accessor and mutator methods in Python are used to access the private data of a class which cannot be accessed from outside the class. In object oriented programming the class object data is encapsulated i.e the object data is kept private and cannot be accessed from outside the object. The access to these private data from outside the object is provided using the Accessor and mutator method in python. These methods are also known as getter and setter methods in python. In this article we will understand Accessor and mutator methods with help of examples. Accessor Methods Accessor method ... Read More

Numpy is a python library used for scientific and mathematical computations. Numpy provides functionality to work with one dimensional arrays and multidimensional arrays. Multidimensional arrays consist of multiple rows and columns. Numpy provides multiple built in functions to interact with multidimensional arrays. In this article we will explore how to access data along multiple dimensions arrays in python numpy. Creating Multidimensional Array in Python Numpy To create a multidimensional array in python we need to pass a list of lists to numpy.array() method of numpy. The list will contain multiple lists each of which represents the rows of the ... Read More
