Code: 
def fib(value):
    previous=0
    result=0
    current=1
    ls = [previous, current]
    
    for i in range(value-2):
        result = current + previous
        previous = current
        current = result
        ls.append(result)
    
    return ls

print("The first 20 Fibonacci numbers are: " + str(fib(20)))
