Gantt Chart in plotly
A Gantt chart is a popular way of representing a project schedule. It is a type of bar chart that illustrates a project schedule, including the start and end dates of tasks and the dependencies between tasks. Gantt charts are widely used in project management to visually represent project plans and schedules.In this technical blog, we will explore how to create a Gantt chart in Python using the Plotly library. Installation and Syntax Before we start creating Gantt charts using Plotly, we need to install the Plotly library in our Python environment. We can install Plotly using pip, which is ...
Read MoreG-Fact 19 (Logical and Bitwise Not Operators on Boolean)
Boolean operators are the foundation of logic in computer science. They are used to perform logical and bitwise operations on binary data. In Python, the logical not operator is used to negate a boolean expression while the bitwise not operator is used to invert the bits in a number. In this blog post, we will explore the logical and bitwise not operators on booleans in Python. Operands and Truth Table The Boolean operators in Python are "and, " "or, " and "not." The "and" operator gives a result of True if both operands are True and False otherwise. The "or" ...
Read MoreReplace two Substrings (of a String) with Each Other
You are given three strings S, A and B. You have to replace every sub−string of S equal to A with B and every sub−string of S equal to B with A. There is a possibility that two or more sub−strings matching A or B overlap. To avoid this confusion about the situation, you have to find the leftmost sub−string that matches A or B, replace it, and then continue with the rest of the string. Input S = “aab”, A = “aa”, B = “bb” Output “bbb” Match the first two characters with A and ...
Read MoreFunctors and their use in Python
Functional programming uses the idea of functors to help programmers create more modular, reusable, and reasonable code. They are a means to enclose a value or a function in an object and then manipulate that object without altering the original object. Functors are a potent tool for writing modular, reusable code in Python and may be implemented using classes. Syntax As Python functors are implemented using classes, a key component of the language, there is no special installation needed. Just build a class with an init method that accepts the original value or function as a parameter and a call ...
Read MoreFunctions that accept variable length key value pair as arguments
Functions that take parameters in the form of variable-length key-value pairs can be defined in Python. This enables more dynamic and versatile functions that can handle a variety of inputs. When a function has to be able to handle arbitrary or optional parameters, this feature is frequently employed. Learn how to use the **kwargs and ** syntax to send a function a variable number of arguments in this technical article. Syntax The **kwargs syntax indicates that the function accepts an arbitrary number of keyword arguments, which are passed in as a dictionary. def function_name(**kwargs): # code block ...
Read MoreFlipping Tiles (memory game) using Python3
Welcome to this blog post where we will be discussing the implementation of a fun game called Flip! using Python. Flip! is a game that involves flipping over tiles on a 4x4 grid to reveal their color. The objective of the game is to flip over all the tiles while making as few moves as possible. In this post, we will go through the implementation of the game using Python and explain the different components of the code. Syntax The following packages are used in this code − itertools − This package provides functions to iterate over collections in ...
Read MoreMinimum number of given Operations Required to Convert a String to Another String
You are given two strings A and B, the task is to convert from string A to string B, if possible. You are allowed to perform only one operation that is to put any character from A and insert it at front. Check if it’s possible to convert the string. If yes, then output minimum number of operations required for transformation. Input output Scenarios Assume we have two strings A and B with values "ABD" and "BAD" respectively the operation need to take to convert the first string to the latter is 1 which is swapping the first two characters. ...
Read MoreFlipkart Reviews Sentiment Analysis using Python
One of the biggest online markets in India is Flipkart, where shoppers can buy everything from gadgets to apparel. Any commercial service must examine the tone of the evaluations in order to enhance their services as a result of the growing number of consumers and their feedback. To detect whether a text exhibits a positive, negative, or neutral attitude, Sentiment Analysis is a Natural Language Processing approach which we will be examining using Python to conduct sentiment analysis on product reviews in this technical blog. Installation and Syntax To perform sentiment analysis on Flipkart reviews, we will need to install ...
Read MoreFind the Order of Execution of given N Processes in Round Robin Scheduling
In this article, you will learn about how to find the order of execution for the given N processes in the Round Robin Scheduling algorithm. But before starting with the code, let’s understand a bit about how this algorithm works. Round Robin Scheduling is a popular CPU scheduling algorithm used in operating systems to allocate CPU time to multiple processes in a fair and efficient manner. In this blog, we will explore how round−robin scheduling works, its advantages and disadvantages, and provide an example to help you understand the concept better. What is Round Robin Scheduling? Round Robin Scheduling is ...
Read MoreHow to place an image into a frame in Tkinter?
To place an image into a Tkinter frame, you can follow the steps given below −Steps −Import the required libraries and create an instance of tkinter frame. To open an image and place it inside the frame, we will use the Pillow (PIL) library.Set the size of the frame using geometry method.Create a frame and specify its height and width. Place the frame at the center of the window using place() method with anchor='center'.Open an image using ImageTk.PhotoImage(Image.open("image"))Next, create a label object inside the frame and pass the image inside the label.Finally, run the mainloop of the application windowExample# Import ...
