What is Dictionary Just like a traditional dictionary has words and their meanings. A dictionary is a data structure that contains data in the form of pairs of keys and values. A key and value pair form an item in the dictionary. A key is usually a string. A dictionary is a collection of key-value pairs. Each key is unique and associated with a value, similar to a real-world dictionary where words (keys) are associated…

What is Tuples In Python? a tuple is an ordered, immutable sequence of elements enclosed in parentheses. Tuples are similar to lists, but they cannot be modified once they are created. This means that you can’t add, remove, or replace elements in a tuple. Here is an example of a tuple: In this tuple, there are five elements: the integers 1, 2, and 3, the string “hello”, and the Boolean value True. What is a…

In Python, a list is a collection of ordered and mutable objects, which means that you can store a sequence of values or objects in a particular order, and you can modify that sequence by adding, removing, or changing the items within it. Python Lists are denoted by square brackets [] and individual items are separated by commas. For example, you can create a list of integers as follows: You can also create a list…

In Python, “operations on numbers and strings” refer to the various ways in which you can manipulate and perform actions on numerical and text-based data. Python provides numerous built-in functions which can be used to perform many complex operations. In this section, we will be exploring some methods of manipulating our numbers and strings. Operations on Numbers: Python supports all the basic arithmetic operations on numbers, such as addition, subtraction, multiplication, division, and exponentiation. Additionally,…

Grouping tasks together in Python refers to the practice of organizing related code into functions or modules to improve code clarity, reusability, and maintainability. Functions are a way to group together a block of code that performs a specific task and can be called from other parts of the code when that task needs to be performed. This can simplify the code, make it more modular and reduce redundancy. For example, instead of copying and…

“Repeating a task” in Python refers to the process of executing the same block of code multiple times. This can be achieved using various looping constructs such as “for” and “while” loops. What is looping? Looping is a programming concept that allows you to execute a block of code multiple times. It is a powerful and essential construct that allows programs to perform repetitive tasks, process large amounts of data, and automate complex workflows. In…

Making decisions in Python refers to the process of using Python programming language and its associated libraries to analyze data, classify information, make predictions, and automate decision-making processes. Python offers a wide range of libraries and tools that make it easy to perform decision-making tasks such as filtering data, classifying data, and making predictions. One of the essential aspects of decision making in Python is data analysis. Python provides libraries like NumPy and Pandas, which…

Calculation in Python refers to the process of performing mathematical operations and operations with variables. Python supports a wide range of calculation operations, including basic arithmetic operations like addition, subtraction, multiplication, and division, as well as more advanced mathematical operations like exponential and logarithmic functions. One of the key advantages of using Python for calculation is that it provides a simple and straightforward syntax for performing operations. For example, to add two numbers in Python,…

Understanding variables and Assigning values What are variables? On a bookshelf, we can see sections that are precisely labeled. So, if we want to place a mathematics book, we will keep it in the section labeled Mathematics, right? so a bookshelf can be used to store the books we want . Similarly, in programming, variables act as containers to store values. These values can be anything, from numbers to text or entire functions. And just…

What is a program? A program is a set of instructions that tells the computer how to perform a specific task. A programming language is a language used to create programs. We will be using Python to create our first program. Does this mean I can make my computer do anything?Yeah, true within its limits.Everything involves giving instructions. E.g.: When you click on the Play button on a media player and the music starts playing,…
