String methods in Python
In Python, a string is a sequence of characters. Strings are used to represent text, and are often used to store and manipulate data. 1 – str.upper(): This method returns a copy of the string with all uppercase letters. For example: 2 – str.lower(): This method returns a copy of the string with all lowercase…
Read MoreWhat is List comprehension and how to use it?
List comprehension is a concise way to create a list using a single line of code. It consists of square brackets containing an expression followed by a for clause, then zero or more for or if clauses. The expressions can be anything, meaning you can put in all kinds of objects in lists. Example 1:…
Read MoreStep-by-Step Process of Implementing Stemming and Lemmatization in Python?
Install the Natural Language Toolkit (NLTK) library. This library provides a range of tools for natural language processing, including stemming and lemmatization algorithms. You can install it using pip install nltk. Import the necessary functions from the NLTK library. For example, to use the Porter stemmer, you would use the following import statement: from nltk.stem.porter…
Read MoreLanguage Detection Project using Machine Learning
Speech recognition is a natural language processing task that requires identifying the language of a text or document. Using machine learning for speech recognition was a difficult task a few years ago due to the lack of much data on language, but now that data is readily available, several powerful machine learning models are already available. So, if you want to learn how to train machine learning models for speech recognition, this article is for you. This…
Read MoreProduct Demand Prediction Project Using Machine Learning
You must have learned that demand for a product change as the price of the product changes. To give a real-life example, if a product is not needed, demand decreases when price increases, and demand increases when price decreases. If you want to know how to use machine learning to predict product demand, this article…

Read MorePython Interview Questions – Part 1
1. What is the difference between indexing and slicing? Indexing is the extracting or lookup one or particular values in a data structure, whereas slicing retrieves a sequence of elements. 2. What is the lambda function? Lambda functions are an anonymous or nameless function. These functions are called anonymous because they are not declared in…
Read MoreWhat are Pickling and Unpickling?
Pickling Converting a Python object hierarchy to a byte stream is called pickling. Pickling is also referred to as serialization. Unpickling Converting a byte stream to a python object hierarchy is called unpickling. Unpickling is also referred to as deserialization. Popular Posts
Read MoreWhat Advantage does the NumPy Array have over a nested list?
NumPy is written in C so that all its complexities are backed into a simple to use a module. Lists, on the other hand, the dynamically typed. Therefore, Python must check the data type of each element every time it uses it. This makes NumPy arrays much faster than lists. NumPy has a lot od…
