Cython fib
Cython can automatically convert many C types from and to Python types, as described in the documentation on type conversion, so we can use a simple list comprehension here to copy the C int values into a Python list of Python int objects, which Cython creates automatically along the way. http://notes-on-cython.readthedocs.io/en/latest/fibo_speed.html

WebIt also gives a nice factor-of-30 speedup for fib(90). Cython The last row measures the performance for the Cython version. Like the C exten‐ sion, it is usable from Python, so it must convert Python objects to C data before it can compute the Fibonacci number, and then convert the result back to Python.

A common example of recursion is the function to calculate the n -th Fibonacci number: def naive_fib(n): if n < 2 : return n else : return naive_fib (n -1) + naive_fib (n -2) This follows the mathematical definition very closely but it’s performance is terrible: roughly O ...
