True that technology can cause a drop in input cost. In a production process, there are three kinds of cost that called input cost, which are the direct material cost, direct labor cost, and overhead cost. Technology usage can make the production process more efficient by reducing labors included in the process. This condition leads to a cost reduction.

Write a program that asks the user for a word. Next, open up the movie reviews.txt file and examine every review one at a time.

Hatshy [7]

Answer:

import numpy as np

word = input("Enter a word: ")

acc = []

with open("Downloads/record-collection.txt", "r") as file:

lines = file.readlines()

for line in lines:

if word in line:

line = line.strip()

acc.append(int(line[0]))

if np.mean(acc) >= 2:

print(f"The word {word} is a positive word")

print(f"{word} appeared {len(acc)} times")

print(f"the review of the word {word} is {round(np.mean(acc), 2)}")

else:

print(f"the word {word} is a negative word with review\

{round(np.mean(acc), 2)}")

Explanation:

The python program gets the text from the review file, using the user input word to get the definition of reviews based on the word, whether positive or negative.

The program uses the 'with' keyword to open the file and created the acc variable to hold the reviews gotten. The mean of the acc is calculated with the numpy mean method and if the mean is equal to or greater than 2 it is a positive word, else negative.
