In this article, we will learn the regex program to display names to be only numbers, letters, and underscores In Java. Validating user input is essential for maintaining data integrity and security in web applications. JavaScript Regex for Name Validation Regular expressions regex is probably more powerful in defining patterns to search for in the text validations. A typical validation is confirming a name consists of only letters (A-Z, a-z), digits (0-9), and underscore (_). To ensure that a name contains only letters we can use the following regex − /^\w+$/ ^: Start of the string ... Read More

Know more about your data: The Graphical Way Histograms & KDE Density Plots Histograms are the most ... Read More
Introduction In NLP tokenizing text into sentences is a very crucial preprocessing task. Tokenization is the process of breaking the text corpus into individual sentences. In NLTK, the default tokenizer does a good task to tokenize text however it fails to do so in cases where the text contains punctuations, symbols, etc. that are non-standard. In such cases, we need to train a tokenizer. In this article let us explore the training of a tokenizer and also see the usage of filter words or stopwords. Tokenizing a Sentence in NLP The default tokenizer in NLTK can be used on the ... Read More
