Calculate the length of words in a string using Python

Finding the length of individual words in a given input string using Python is a problem that must be solved. We want to count the number of characters of each word in a text input and display the results in a structured style such as a list. The task requires breaking up the input string and separating each word. Then calculate the length of each word based on the number of characters in it. The basic goal is to create a function or procedure that can efficiently receive input, determine word length, and output results in a timely manner. Addressing this issue is critical in a variety of applications, including text processing, natural language processing, and data analysis, where word length statistics can provide insightful information and enable additional analysis. Methods used Use loops and split() function Use map() function with len and split() Use

Mastering HTML5: Constrained Validation

HTML5 brings us many very good advantages. Aside from common issues like unifying the error model, introducing new semantic tags, or simplifying document types, one of the biggest improvements is constraint validation for forms. What would the web be like without forms? Constraint validation attempts to improve the usability of web forms. The browser can directly inform the user of the possibility of invalid values, rather than sending the form to the server, which then evaluates it as invalid, comes back to the client and is ultimately adjusted by the user. This not only reduces network traffic but also improves page usability. It is important to note that constraint validation does not replace server-side validation. Additionally, JavaScript-based solutions may still be useful. Generally speaking we always have to implement server side validation

Write a program in Java to replace all characters in a file with '#' except specific words

The split() method of String class. Split the current string into matches of the given regular expression. The array returned by this method contains each substring of this string that is terminated by another substring that matches the given expression or terminates at the end of the string. The replaceAll() method of String class accepts two strings representing regular expressions and a replacement string and replaces the matching value with the given string. Replace all characters in the file except specific words with "#" (one way) - read the contents of the file into a string. Create an empty StringBuffer object. Use the split() method to split the obtained string into a String array. all over
