The Joy Of Computing Using Python Week 4: Programming Assignment 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)
Answer
n = int(input())
sum_of_squares = 0
for i in range(1, n+1):
sum_of_squares += i**2
print(sum_of_squares)
The Joy Of Computing Using Python Week 4: Programming Assignment 2
Write a Python 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)
Answer
n = int(input()) result = 2 ** n print(result)
The Joy Of Computing Using Python Week 4: Programming Assignment 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
567898765
Answer
n=int(input())
max_row=1
max_row1=1
for row in range(1,n+1):
b=0
for space in range(1,n-row+1):
print(" ",end="")
a=row
Left=list()
while(a!=max_row1):
if a>9:
Left.append(str(b))
b=b+1
else:
Left.append(str(a))
a=a+1
if row==n:
print(("".join(Left)+str(max_row)+"".join(Left[::-1])),end="")
else:
print(("".join(Left)+str(max_row)+"".join(Left[::-1])))
if (max_row+2>9):
max_row=-1
max_row+=2
max_row1+=2
