### fibonacci
Generates a list containing the Fibonacci sequence up to the nth term.
Starting with 0 and 1, adds the sum of the last two numbers of the list to the end of the list using ```list.append()``` until the length of the list reaches n. If the given nth value is 0 or less, the method will just return a list containing 0.
``` python
def fibonacci(n):
if n <= 0:
return [0]
sequence = [0, 1]
while len(sequence) <= n:
# Add the sum of the previous two numbers to the sequence
next_value = sequence[len(sequence) - 1] + sequence[len(sequence) - 2]
sequence.append(next_value)
return sequence
```
``` python
fibonacci(7) # [0, 1, 1, 2, 3, 5, 8, 13]
```
