Read MorePython Program to Check Overlapping Prefix - Suffix in Two Lists
Generally, a prefix is a sequence of characters that appear at the beginning of a string or list, and a suffix is a sequence of characters that appear at the end of a string or list. For example, when we consider the list [1, 2, 3, 4, 5], a prefix could be [1, 2, 3] and a suffix could be [3, 4, 5]. Notice how they overlap at element 3. Checking for overlapping prefixes and suffixes in two lists involves comparing elements to determine if the end of one list matches the beginning of another list. This concept ...
Read MorePython program to check if the given string is IPv4 or IPv6 or Invalid
An IP address is the short form of Internet Protocol address, which is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It serves as an identifier for the device, allowing it to send and receive data over the network. IPv4 (Internet Protocol version 4): This is the most widely used version of IP addresses. It consists of four sets of numbers separated by periods, such as "192.168.0.1". Each set can have a value between 0 and 255. IPv6 (Internet Protocol version 6): This is the newer version ...
Read MorePython Program to check if elements to the left and right of the pivot are smaller or greater respectively
In Python, a pivot is an element used to partition data into two groups: elements smaller than the pivot on the left, and elements greater than the pivot on the right. This concept is commonly used in sorting algorithms like quicksort. Let's explore different methods to check if elements to the left of a pivot are smaller and elements to the right are greater than the pivot value. Using Loops We can iterate through the array using loops to check each element against the pivot value ? def check_pivot_with_loops(arr, pivot_index): pivot ...
Read MorePython Program to check date in date range
In this article we will learn how to check if a given input date falls within a specified date range. Python provides several approaches to accomplish this task, each with its own advantages. Using the datetime() Function The datetime module offers classes to manipulate dates and times. The datetime() function accepts year, month, and day as input arguments and returns a datetime object that can be easily compared. Example In this example we check if the date 25−05−2023 falls within the range of 01−01−1991 to 31−12−2023 ? from datetime import datetime def is_date_in_range(date, ...
Read MorePython program to Check all strings are mutually disjoint
String is one of the data structures which holds data enclosed in double quotes or single quotes. It is immutable, meaning once we define the data we cannot change or modify it. In Python we have a function called str() which takes any data as input and returns the string as output. Mutually disjoint means no two strings have any common characters. There are different ways to check if all strings are mutually disjoint. Let's explore each approach. Using Nested Loops This approach uses nested loops to compare each pair of strings by converting them to sets ...
Read MorePython program to change the value of a dictionary if it equals K
A dictionary is one of Python's most versatile data structures, storing data in key-value pairs using {} curly braces. Dictionary keys are unique, values can be repeated, and the structure is mutable, allowing modifications after creation. In this article, we'll explore different techniques to change dictionary values that equal a specific value K. Let's examine each approach with practical examples. Using a For Loop The for loop iterates through dictionary items and updates values when they match our target value K ? Example def change_value_if_equals_K(dictionary, K, new_value): for key, value ...
Read MorePython program to calculate gross pay
Gross pay is the total amount paid to an employee before taxes and deductions. It includes base salary, bonuses, overtime, and reimbursements. The basic formula is: Hours worked × Pay per hour = Gross pay For example, if an employee worked 40 hours at ₹500 per hour: 40 × 500 = ₹20, 000 gross pay Let's explore different methods to calculate gross pay using Python. Basic Gross Pay Calculation The simplest approach calculates gross pay using hours worked and hourly rate ? def calculate_gross_pay(hours, hourly_rate): ...
Read MorePython program to calculate square of a given number
A square is defined as the multiplication of a number by itself. The square of a number n is given as n2. Mathematically, we can represent the square of a number as: n² = n × n Python provides several approaches to calculate the square of a number. Let's explore the most common methods. Using Exponential Operator (**) The exponential operator (**) performs exponent arithmetic operations. To find the square, we raise the number to the power of 2. Syntax: n ** 2 Example Here we calculate the square of 25 using the ...
Read MorePython program to calculate Date, Month and Year from Seconds
When working with timestamps, you often need to convert seconds (Unix epoch time) into readable date components. Python provides several approaches using the datetime module, time module, or manual calculations with divmod(). Using datetime Module The datetime module offers classes to manipulate dates and times. The utcfromtimestamp() function converts seconds since epoch (January 1, 1970) into a datetime object. Syntax datetime.datetime.utcfromtimestamp(seconds) Example Here we convert 1706472809 seconds to extract the day, month, and year components ? import datetime def calculate_date(seconds): date = datetime.datetime.utcfromtimestamp(seconds) ...
