Python modules

 A Python module is a file containing Python definitions and statements. A module can define functions, classes, and variables. A module can also include runnable code. Grouping related code into a module makes the code easier to understand and use. It also makes the code logically organized. The import statement - when the interpreter encounters an import statement, it imports the module. of the module is present in the search bath. A search bath is a list of directories that the interpreter searched for importing a module. Example- create a simple calc.py module, in which we define two functions, one add and another subtract def add (x, y): return (x+y) def subtract (x, y): return (x-y) Now, to import the module calc⋅py, we need to put the following command at the top of the script- Syntax-import module import calc print (calc.add (10,2)) The from statement- Python's from statement is use to import specific attributes from a module without importing the module as a whole.

Python libraries

 #Here's a simple Python program that uses the `matplotlib` library to create a pie chart for the sales distribution of different fruits in a store: import matplotlib.pyplot as plt # Sample data fruits = ['Apples', 'Bananas', 'Cherries', 'Oranges', 'Strawberries'] sales = [30, 20, 25, 15, 10] # Create a pie chart plt.figure(figsize=(8, 8))  # Set the figure size plt.pie(sales, labels=fruits, autopct='%1.1f%%') plt.title('Sales Distribution of Different Fruits in a Store')   # Show the pie chart plt.show() 2. Histogram  #The `hist()` function is used to create a histogram, which is a graphical representation of the distribution of numerical data. It groups the data into bins and counts the number of observations in each bin. #### Example Code for `hist()`:   import matplotlib.pyplot as plt import numpy as np # Generate random data data = np.random.randn(1000) # 1000 random numbers from a normal distribution # Create a histogra...

What is software project management?

 Software project management is the integration of management techniques into software development. The need for such integration has its root in the 1960s Software Project Management (SPM) in Software Engineering (SE) involves planning, executing, and controlling software projects to deliver high-quality software products on time and within budget. It encompasses a range of activities and processes to ensure the successful completion of software development projects. Here are the key aspects of software project management in SE:  Project Initiation:  Define project objectives and scope.  Identify stakeholders and their requirements.  Prepare a project charter or initial project plan.  Project Planning: Create a detailed project plan outlining tasks, milestones, timelines, and resource allocation. Develop a Work Breakdown Structure (WBS) to break the project into manageable components. Estimate costs, effort, and resources required. Define project risks and develop a risk mana...

WHAT IS A PROJECT ?

What is a project? a "project" is a temporary and unique endeavor undertaken to achieve a specific set of goals and objectives. Projects in SPM typically involve the development of software products or systems. A project is a group of tasks that need to complete to reach a clear result. A project also defines as a set of inputs and outputs which are required to achieve a goal. Projects can vary from simple to difficult A project is “a temporary endeavor undertaken to create a unique product, service, or result.” Operations, on the other hand, is work done in organizations to sustain the business. Projects are different from operations in that they end when their objectives have been reached or the project has been terminated. Ex: A company develops a driverless car, A team of students creates a smartphone application and sells it online A program is a set of related projects managed in a coordinated way. The underlying motivation is that coordination allows one to achieve add...

Machine learning

 ***Source:IBM cloud**   Machine Learning Machine learning focuses on applications that learn from experience and improve their decision-making or predictive accuracy over time.    What is machine learning?  Machine learning is a branch of artificial intelligence (AI) focused on building applications that learn from data and improve their accuracy over time without being programmed to do so. In data science, an algorithm is a sequence of statistical processing steps. In machine learning, algorithms are 'trained' to find patterns and features in massive amounts of data in order to make decisions and predictions based on new data. The better the algorithm, the more accurate the decisions and predictions will become as it processes more data. Today, examples of machine learning are all around us. Digital assistants search the web and play music in response to our voice commands. Websites recommend products and movies and songs based on what we bought, watched, or l...
