Question 1
Take an input N as an integer and write a program to display a right angle triangle with N rows and N columns.
Input
5
Solution:
num = int(input())
k = 1
for i in range(0, num):
for j in range(0, k):
print("* ", end="")
k = k + 1
print()These are answers of The Joy of Computing using Python Assignment 3 Answers
Question 2
Write a program to take an input N and print Fibonacci sequence till N terms.
The Fibonacci sequence is a set of integers (the Fibonacci numbers) that starts with a zero, followed by a one, then by another one, and then by a series of steadily increasing numbers. The sequence follows the rule that each number is equal to the sum of the preceding two numbers.
Input
7
Output
0
1
1
2
3
5
8
Explanation: since the input is 7 there are seven terms. The first two terms are always 0 and 1. The third term is sum of first two terms. The fourth term is sum of second and third terms and so on.
Solution:
# Python program to display the Fibonacci sequence
n = int(input())
def recur_fibo(n):
if n <= 1:
return n
else:
return(recur_fibo(n-1) + recur_fibo(n-2))
# check if the number of terms is valid
if n <= 0:
print("Plese enter a positive integer")
else:
for i in range(n):
print(recur_fibo(i))These are answers of The Joy of Computing using Python Assignment 3 Answers
