You changed your code, the problem is now in line 7. The while loop should continue as long as the fib number is less than the_number_has_to_be_bigger_than, but it is using position_in_fib_sequence instead. So, the fib sequence is 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ... Say I want the second fib number greater than 8. Your code will give me the second fib number greater than 2, which is 8.
Ooh I understand!!
It is working for a part. If I want the 2nd fibonacci number bigger than 4 it is giving 8. But if I give the 2nd bigger than 5 it gives also 8.
position_in_fib_sequence = int(input("Which fibonaccinumber do you want to know?"))
the_number_has_to_be_bigger_than = int(input("Bigger than?"))
G1 = 0
G2 = 1
while G2 < the_number_has_to_be_bigger_than:
G1, G2 = G2, G1 + G2
for i in range(position_in_fib_sequence-1):
G1, G2 = G2, G1 + G2
print("The", str(position_in_fib_sequence) + "th", "fibonaccinumber bigger than", the_number_has_to_be_bigger_than, "is", G2)
That's because 5 is a fibonacci number. You want the < on line 7 to be a <=, so that coming out of that loop the current fib number is guaranteed to be larger than the number provided.

Thank you for your help and let me understand! I just began programming so it's still difficult for me.
