Question

ПИТОН В массиве хранятся сведения об оценках 25 учеников по химии. Определить количество неуспевающих по химии учеников.

Answer 1

Будем считать ученика неуспевающим, если он имеет оценку '2'.

Заполним список из оценок 25 учеников случайными отметками от 2 до 5 и выведем на экран количество неуспевающих.

from random import randint

size = 25

marks = [] * size

count = 0

for i in range(size):

   marks.append(randint(2, 5))

   if marks[i] < 3:

       count = count + 1

print('Оценки учеников по химии: ', marks)

print('Количество неуспевающих учеников: ', count)

Answer 2

Calculating the Number of Underperforming Chemistry Students

To determine the number of underperforming students in the chemistry class, we can use Python to analyze the array containing the students' grades. We'll assume that a failing grade is anything below a certain threshold, such as 60%.

Here's a Python code snippet to achieve this:

# Assuming the grades are stored in an array called 'chemistry_grades'
chemistry_grades = [/*insert the grades of 25 students here*/]

# Counting the number of underperforming students
failing_students = sum(grade < 60 for grade in chemistry_grades)

In this code snippet, we first define the array `chemistry_grades` containing the grades of the 25 students. Then, we use a list comprehension to count the number of grades below 60, which represents the failing students.

The number of underperforming students in the chemistry class is equal to the value of the variable 'failing_students'.

This Python code efficiently calculates the number of underperforming students based on the given grades.
