Question 1
\Write a program that takes a number `n` as input and prints the sum of the squares of the first `n` positive integers.
Example:
If n = 4, the program should output 30 (1^2 + 2^2 + 3^2 + 4^2 = 30)
Solution:
def sum_of_squares(n):
sum = 0
for i in range(1, n+1):
sum += i**2
return sum
n = int(input())
print(sum_of_squares(n))These are answers of The Joy of Computing using Python Assignment 4 Answers
Question 2
Write a program that takes a number `n` as input and prints the nth power of 2.
Example:
If n = 4, the program should output 16 (2^4 = 16)
Solution:
def power_of_two(n):
return 2**n
n = int(input())
print(power_of_two(n))These are answers of The Joy of Computing using Python Assignment 4 Answers
Question 3
Write a program that takes a number `n` as input and prints a pyramid of numbers with `n` rows.
Example:
If n = 5, the program should output the following
1
232
34543
4567654
567898765Solution:
def pyramid(n):
for i in range(1, n+1):
spaces = " " * (n - i)
numbers = ""
for j in range(i, 2 * i):
numbers += str(j % 10)
for k in range(2 * i - 2, i - 1, -1):
numbers += str(k % 10)
print(spaces + numbers)
n = int(input())
