A nested list is a list that has lists as elements. For example: [[1, 2, 3], [4, 5, 6], [7, 8, 9]] is a nested list as it has 3 lists ([1, 2, 3], [4, 5, 6], and [7, 8, 9]) as its elements. To flatten a list of lists (nested list), i.e., to convert a 2D list into a 1D list, there are different ways such as Nested for loop, List Comprehension, Built-in Functions, or by importing libraries in Python. In this article, we will discuss the above methods to flatten a list in Python. Using for loops For ... Read More
To extract decimal numbers from a string in Python, regular expressions are used. A regular expression is a group of characters that allows you to use a search pattern to find a string or a set of strings. RegEx is another name for regular expressions. The re module in Python is used to work with regular expressions. In this article, we will learn how to extract decimal numbers from a string in Python using regular expressions. To retrieve non-digit characters from a string, we use the following regular expression - \d+\.\d+ Where, \d returns a match where the string contains ... Read More
A tuple in Python is an ordered collection of items that cannot be changed once, making it immutable. This allows duplicate values and can hold elements of different data types, such as strings, numbers, other tuples, and more. This makes tuples useful for grouping related data while determining that the content remains fixed and unchanged. How to Display an Entire Tuple in Python? To display a complete tuple in Python, we can simply use the print() function. Here's a basic example - tuple = (3, 4, 5, 6, 7, 1, 2) print(tuple) The result is obtained as follows - ... Read More
By default, Python regular expressions (regex) look for case-sensitive matches. That is, the terms "apple" and "Apple" are not synonyms. But sometimes we want to search without consideration for uppercase or lowercase. This is referred to as a case-insensitive match. This chapter teaches you how to create case-insensitive regexes in Python without using re.compile(). What is a Regular Expression? A regular expression (regex) is a pattern that enables you to find strings like - Emails Phone Numbers Names Or any pattern. To interact with regular expressions, we use the Python built-in module re. Import the re Module Before ... Read More
In this article, we will see the concept of B-regular expressions in Python. Regular expressions (regex) are a useful tool for matching patterns in strings. In Python, the re module helps you to work with regex patterns. What is a B Regular Expression? A 'B' regular expression is a type of regex that searches and matches particular patterns within a string. For example, it can be used to find out whether a string starts or ends with a given letter or whether it matches the pattern's set criteria. Use the re Module For using regular expressions in Python, you need ... Read More
Regular expressions are a useful tool for searching and manipulating strings in Python. Among the several patterns and methods available, the [d+] expression is used to match one or more digits in a string. In this article, we will go over the [d+] regular expression pattern, the way it is used, and five code examples with step-by-step explanations to help you understand and apply it to your Python projects. Understanding the [d+] Pattern Before we see the code examples, let us first understand the [d+] pattern. So basically [d+] is a combination of two elements - ... Read More
Refrigerator and Air Conditioner (AC) are both electrical appliances that are used to reduce the temperature of a closed space by transferring the heat of the closed space to another place. Both AC and refrigerator work on the principle of heat-sinks, i.e., these devices transfer the heat from a source (or closed space) to another place called sink. Read through this article to find out how Air Conditioners are different from Refrigerators. What is an Air Conditioner? An Air Conditioner is an electrically operated cooling device which is generally used to cool a large closed space such as a ... Read More
The re module provides tools while working with Python's regular expression (regex), which allows us to search for any specific pattern within the strings. Using the 're' module provides two functions named match() and search(), which accept a pattern (regular expression) and return True or False. The match() function returns 'None' if no pattern is detected, or it returns the match in the form of an object (in case of a match). In addition to these, we can also use the fullmatch() function to get a boolean result from a regular expression. ... Read More

What is QCommerce?Qcommerce combines the rapidity of on-demand delivery with the ease of e-commerce. It includes online platforms that deliver goods—mostly food and other necessities in short time. This concept . Qcommerce uses hidden shopfronts, AI-powered platforms, and other logistics to do this. These help in inventory location and delivery time optimization.How Fast Does Quick Commerce Operates?Quick commerce uses what are known as "dark stores, " which are micro-warehouse models. These are tiny fulfilment facilities that are positioned thoughtfully around crowded cities. By keeping in-demand commodities in these stores, businesses may drastically cut down on delivery times. Q-commerce platforms optimize ... Read More
