- (textblob.utils Utility Functions) TextBlob’s textblob.utils module offers several utility functions for cleaning up text, including strip_punc and lowerstrip. You call strip_punc with a string and the keyword argument all=True to remove punctuation from the string. You call lowerstrip with a string and the keyword argument all=True to get a string in all lowercase letters with whitespace and punctuation removed. Experiment with each function on Romeo and Julietarrow_forwardPlease Explain the Steps. (In Java Programming) See expected output below. Create a new Java application called "WeightedAvgDropSmallest" (without the quotation marks) according to the following guidelines. The program prompts the user for five to ten numbers all on one line, separated by spaces, calculates the weighted average of all those numbers except the lowest n numbers, where n and the weight are also given by the user, and displays all the numbers, the weight, the number of lowest numbers dropped, and the calculated average to the user. The program uses methods to: Get the numbers used to calculate the average. Get the number of lowest numbers to drop before calculating the average. Get the weight, a double greater than 0 and less than or equal to 1. Calculate the weighted average of the numbers (except the lowest n numbers) entered by the user. Print the results. 1. The first method should take no arguments and return an array list of doubles. 2. The second method…arrow_forwardQUESTION 1 Evaluate the following expressions, assume the following declarations: int x = 4; int y = 9/2; int num = 6; num *= x + y; What is the value of the num after expression is evaluated?arrow_forward
- Program Purpose - Professional Athletes often hire other professionals to help take care of matters for them. We will group them in four categories: Lawyers, Personal Assistants, Agents, and Trainers. They all get paid a percentage of the athlete's total yearly salary. Lawyers - 10%, Personal Assistants - 3%, Agents - 7%, and Trainers - 5% . Prompt the user to enter the athlete's salary for the year (ensure that the entered value is positive). The user should then enter the name and category of each of the hired professionals. The athlete should be able to hire as many professionals in each category as he/she wants, even if it is more than he/she can afford. Based on the category, calculate the amount that each professional should be paid. After all data has been entered, print the names of each professional hired, how much each is being paid, the total amount the athlete paid, and how much the athlete has left.arrow_forwardWrite a single scanf statement that reads user-entered time (three integers) and discards the user-entered characters between the numbers, in order, for hour (hh), minute (mm), and second (ss). For example, the user may enter the time as 12:23:21 or 12 23 21 or 12, 23, 21.arrow_forwardWrite an expression that will cause the following code to print "Equal" if the value of sensorReading is "close enough" to targetValue. Otherwise, print "Not equal". Hint: Use epsilon value 0.0001. Ex: If targetValue is 0.3333 and sensorReading is (1.0/3.0), output is:Equal #include <iostream>#include <cmath>using namespace std; int main() { double targetValue; double sensorReading; cin >> targetValue; cin >> sensorReading; if (/* Your solution goes here */) { cout << "Equal" << endl; } else { cout << "Not equal" << endl; } return 0;}arrow_forward
