The task is to create a One-Time Password (OTP) by squaring and concatenating the odd digits of a given number. Input Output Scenarios Following are the input-output scenarios for creating an OTP by squaring and concatenating the odd digits of a number Input number = 123456789 Output OTP: 19254981 The odd digits in the number are 1, 3, 5, 7, 9. Squaring each of these digits gives us 1, 9, 25, 49, 81. Concatenating these squared digits together gives us the OTP 19254981. Input: 54321 Output: 2591 The odd digits in the input number are 5, 3, and ... Read More
Creating a list centered on zero involves generating a sequence of numbers where zero is positioned in the middle of the list. While the size of the list can be customized, it is often preferred to use an odd number to ensure symmetrical distribution of elements around zero. In this article, we will discuss the different approaches to creating a list centered on zero using Python programming. Approach We can follow the below steps to create a centered list − Determine the desired size of the list. Let's call this value n. If n is an odd number, it ... Read More
Strings in Python can contain any sequence of characters, including letters, numbers, symbols, and whitespace. It can represent text, numbers, or any other type of data that can be represented as a sequence of characters. In Python, strings are enclosed in single quotes ('') or double quotes (""). Multiline strings can be created using triple quotes (''' or """). Here are a few examples of valid Python strings: "Hello, World!" "12345" "Python is awesome!" Counting the number of characters in a string involves determining the total count of individual characters within the string. Python offers various techniques for ... Read More
A meter is the fundamental unit of length in the International System of Units (SI) and is used worldwide. It is defined as the length of the path traveled by light in a vacuum during a time interval of 1/299, 792, 458 of a second. Meters are commonly used in scientific, engineering, and everyday contexts. The yard, on the other hand, is a unit of length commonly used in both the British imperial and US customary systems of measurement. It is an English unit defined as 3 feet or 36 inches. It is defined as exactly 0.9144 meters. Yards are ... Read More
When working with text processing and analysis tasks, it is frequently required to count the vowels, lines, and characters in a text file. The goal is to determine the total counts of vowels, lines, and characters present in the file. Python provides various methods and techniques that can be used to accomplish these counting tasks effectively and efficiently. In this article, we will discuss different approaches for counting vowels, lines, and characters in a text file using Python programming. Approach By following the below steps, we can effectively count the vowels, lines, and characters in a text file using Python. ... Read More
When working with text processing and analysis tasks, it is often necessary to count the words in a text file. The objective is to determine the total number of words present in the file. Python offers several modules and functions that can efficiently and effectively perform word-counting tasks. In this article, we will explore different approaches to obtaining the total word count from a text file using Python programming. Approach Following are the steps to count words in a text file − Open the text file − Use the open() function to open the text file in read mode. ... Read More
Blank spaces in a text file refer to the empty spaces or gaps between words, sentences, or characters. These spaces are typically represented by the space character (' ') or other whitespace characters, including tab ('\t'), newline (''), carriage return ('\r'), form feed ('\f'), and vertical tab ('\v'). These characters, as per the Unicode standard, represent empty space or formatting elements in the text. When counting the number of blank spaces in a text file, we are essentially looking for these whitespace characters to determine the frequency or distribution of spaces within the text. This information can be useful for ... Read More
A dictionary in Python is an unordered collection of key-value pairs. It is a data structure that allows you to store and retrieve values based on a unique key associated with each value. Keys in a dictionary are used to uniquely identify values, and they must be immutable, such as strings, numbers, or tuples. On the other hand, the associated values in a dictionary can be of any data type and can be mutable. When we want to convert a dictionary values to strings, we need to iterate over the dictionary using a loop and convert each value to a ... Read More
Float to exponential conversion involves transforming a decimal number, represented as a float, into exponential notation, also known as scientific notation. Exponential notation is commonly used for expressing very large or very small numbers in a concise manner, particularly in scientific and mathematical calculations. On the other hand, a float is a data type used to store real numbers, including both whole and fractional numbers. In Python, floats are commonly used to represent floating-point numbers. The process of converting a float to exponential can be achieved using various approaches in Python, such as using the format() function, f-string formatting, or ... Read More
Exponential notation also known as scientific notation, is a way to express numbers that are very large or very small using a combination of a coefficient and an exponent. It is commonly used in scientific and mathematical calculations. In exponential notation, a number is expressed as the product of a coefficient and a power of 10. The coefficient is typically a decimal number between 1 and 10, and the power of 10 indicates the scale of the number. For example − The number 1, 000, 000 can be expressed as 1 x 10^6 or 1e+6 in exponential notation. The ... Read More
