Python program to Generate Fibonacci Sequence Using Function

def fibonacci(list_item):
 f1 = f2 = 1
 print(f1, f2, end=' ')
 while list_item > 2:
     num = f2
     f2 = f1 + f2
     f1 = num
     print(f2, end=' ')
     list_item -= 1
 print()
x = int(input("Insert range of Fibonacci sequence: "))
fibonacci(x)

Insert range of Fibonacci sequence: 5
1 1 2 3 5

Insert range of Fibonacci sequence: 9
1 1 2 3 5 8 13 21 34
