Срочно помогите решить задачки по Python

1)

 def find_max_mean_line(arr): 

    max_mean = 0 

    max_mean_line = 0 

    for i in range(len(arr)): 

        line_mean = sum(arr[i]) / len(arr[i]) 

        if line_mean > max_mean: 

            max_mean = line_mean 

            max_mean_line = i 

    return max_mean_line + 1 

 

arr = [[1, 2, 3, 4, 5], [6, 7, 8, 9, 10], [11, 12, 13, 14, 15], [16, 17, 18, 19, 20], [21, 22, 23, 24, 25], [26, 27, 28, 29, 30]] 

print(find_max_mean_line(arr)) 

 

2)

 def fill_spiral(arr): 

    row_start = 0 

    row_end = len(arr) - 1 

    col_start = 0 

    col_end = len(arr[0]) - 1 

    num = 1 

    while row_start

Задача 1

Задача 2

Задача 3
import numpy as np

print(arr)
Задача 4
import numpy as np
arr = np.random.randint(1, 100, (6, 5))
arr = arr[np.argsort(-np.sum(arr, axis=1))]
print(arr)
