how to generate a sewuence of febanachi numbers python code example
Example 1: fibonacci sequence python
# WARNING: this program assumes the
# fibonacci sequence starts at 1
def fib(num):
"""return the number at index num in the fibonacci sequence"""
if num <= 2:
return 1
return fib(num - 1) + fib(num - 2)
print(fib(6)) # 8
Example 2: python fibonacci sequence generator
number1 = 0
print('1:', number1)
number2 = 1
for count in range(2, 101):
print(count, ':', number1 + number2)
number1 += number2
number2 = number1 - number2
