nth Term of Fibonacci Series in Python
An interesting feature of Fibonacci numbers is that ratio of consecutive Fibonacci numbers is equal to 1.618, also known as the Golden Ratio.
def elementInFibonacciSeriesAtPosition(enteredPosition):
a, b = 0, 1
fibonacciNumbers = []
while True:
fibonacciNumbers.append(a)
a, b = b, a+b
if len(fibonacciNumbers) == enteredPosition:
print(fibonacciNumbers.pop())
break
elementInFibonacciSeriesAtPosition(11) # 55
