## Functional prodigy

```
def fib(n):
if n <= 1:
return n
return fib(n-1) + fib(n-2)
```

## Meta Functional Expert

```
def fib(a, b, nth=0, current=0):
if nth == current:
return a
return fib(b, a + b, nth, current+1)
def main():
series = [fib(0,1,n) for n in range(50)]
print(series)
```

## One Liner Wizard

```
f = lambda n: n if n <= 1 else f(n-1) + f(n-2) # f and not fib because functional laws
```

## The Librarian

```
pip install fibonacci
```

```
from fibonacci import fibo
series = [fibo(n) for n in range(10)]
print(series)
```

## Classy Theorist

```
class Fibonacci:
def __init__(self, nth):
self.nth = nth
self.a = 0
self.b = 1
self.current = 0
def get(self):
while True:
if self.current == self.nth:
return self.a
self.a, self.b = self.b, self.a + self.b
self.current += 1
def main():
f = Fibonacci(100)
# God bless getters
print(f.get())
```

## Closure Fanatic

```
from functools import wraps
def closo_fibo_stream():
# precious closures
a, b = 0, 1
@wraps
def wrapper(*args, **kwargs):
nonlocal a, b
current = a
a, b = b, a + b
return current
return wrapper
def main():
streamer = closo_fibo_stream()
series = [streamer() for i in range(10)]
print(series)
```

## Lazy Idealist

```
def lazy_fibo():
a, b = 0, 1
while True:
yield a
a, b = b, a + b
def main():
from itertools import islice
for n in islice(lazy_fibo(), 100):
print(n) # i feel good
```

## OO based Lazy conservative

```
# refactored into class coz why not??
class LazyFibo:
def __init__(self):
self.a = 0
self.b = 1
def __iter__(self):
while True:
yield self.a
self.a , self.b = self.b, self.b + self.a
def main():
from itertools import islice
for n in islice(LazyFibo(),10):
print(n)
```

## Generator Magician

```
def fib_magico(a, b):
yield a
yield from fib_magico(b, a + b)
def main():
from itertools import islice
for n in islice(fib_magico(0, 1), 10):
print(n)
```

## Iterator Maniac

```
class fib_iter:
def __init__(self, n):
self.n = n
self.current = 0
self.a = 0
self.b = 1
def __next__(self):
if self.current > self.n:
raise StopIteration("don't care anymore")
current = self.a
self.a, self.b = self.b, self.a + self.b
self.current += 1
return current
class fib:
def __init__(self, n):
self.n = n
def __iter__(self):
return fib_iter(self.n)
def main():
for i in fib(10):
print(i)
```

## Rob Pike

```
def fib(n):
res = []
a, b = 0, 1
for i in range(n):
res.append(a)
a, b = b, a + b
return res
```

That was pretty neat 😎
