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…
