Write a program that receive the index and return the corresponding value.

Q.

(a). Write a program that receive the index and return the corresponding value.

(b). Write a program that receives a Fibonacci term. And return and returns a number telling which term it is .

Answer :-

(a).

a = eval (input('Enter the list ='))
b = int (input ("Enter the index number ="))
if b< len(a):
    print ("value is =", a[b])
else :
    print ("index out of range")

(b).

term= int (input ("Enter Fibonacci Term ="))
fib = (0,1,1)
for i in range(term):
    fib = fib + ( fib [ i + 1] + fib [ i + 2 ],)
for j in range(len(fib)):
    if term == fib[ j ] :
        break
if j == len(fib)-1:
    print("Not Exist in Fibonacci Series ")
else :
    print("Fibonacci Series :- ", fib [ 0 :j +1] )
    print()
    print("This is ",j + 1,"th term of Fibonacci ")

Output :-

(a)

Enter the list = [1,2,3,4,5,6,7,8,9]
Enter the index number = 8
Value is = 9
>>> 

Enter the list = [12,78,69,52,23,32,41]
Enter the index number = 7
Index out of range
>>> 

(b)

Enter Fibonacci Term =55
Fibonacci Series :-  (0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55)

This is  11 th term of Fibonacci
>>> 

Enter Fibonacci Term =30
Not Exist in Fibonacci Series
>>>
