Program 9: Write a function fibonacci(num) that takes num as an input and prints the fibonacci series until num
terms. Invoke the function to print the fibonacci series for the user-entered nth term.

Ans. def fibonacci(num):
'''

Objective : To calculate the fibonacci series
Input Parameter : num - numeric value
Return Value : None
'''
x = 0
y = 1

if num == 1:
print(x)
else:

print(x,y, end=' ')
for i in range(2,num):
z = x + y
x = y
y = z
print(z, end=' ')

num = int(input("Enter a number: "))
print("The fibonacci series is: ")
fibonacci(num)

Program 10: Write a Python program that accepts two numbers from the user and displays their greater common
divisor (GCD) and least common multiple (LCM).

Ans. def GCD(num1,num2):
'''
Objective : To calculate the GCD of 2 numbers
Input Parameters : num1,num2 - numeric value

Return Value : gcd - numeric value
