Question

знайдіть сер арифметичне пайтона

Answer 1

1:

lst = [i for i in range(100, 1000) if i // 100 == i % 10]

print(sum(lst) / len(lst))

2:

lst = []

for _ in range(int(input('n = '))):

  n = int(input())

  if n < 10:

      lst.append(n)

print(sum(lst) / len(lst))

3:

lst = []

for i in range(1000, 10000):

  sti = str(i)

  if all(([sti.count(c) == 1 for c in sti])):

      lst.append(i)

print(lst)

4:

n = int(input('n = '))

print(len([i for i in range(1, n + 1) if not n % i and not i % 2]))

5:

lst = [i for i in range(100, 1000) if str(i) == str(i)[::-1] and len([i for i in range(1, i)]) == 1]

print(lst)

6:

from math import factorial as fa

print(sum([fa(i) for i in range(1, int(input('n = ')) + 1)]))
