IN PYTHON

Write a program that will prompt the user to an integer, assign to variable n. The program should also generate the sum of the first n Fibonacci numbers: 1,1,2,3,5,8,13, , where a Fibonacci number is the sum of the two numbers before it (except the first two Fibonacci numbers) 2=1+1, 3=2+1, 5=2+3, 8=3+5, 13=5+8, etc. The sum of the first 4 Fibonacci numbers I 1+1+2+3 = 7. Use a for loop.
