CPU Benchmark - single core speed test with Fibonacci Sequence in Python

In this short article, I would like to show Fibonacci Sequence test that is run on a single core. The test source code was converted from C++ to Python - check source article.

Example test.py file:

import time

def get_current_time():
    return round(1000 * time.time())

a, b = 0, 1

print('Started!');
  
t1 = get_current_time();

i = 0
while i < 10000:
    j = 0
    while j < 1000000:
        tmp = b
        b = a + b
        a = tmp
        j = j + 1
    i = i + 1

t2 = get_current_time();
dt = t2 - t1;

print('Finished!');

print('Result: ', b);
print('Time: ', 0.001 * dt, 's');

Running with python:

py test.py

Example output:

Started!
Finished!
Result:  ...
Time:  >199760 s

Conclusion: execution time is very long what is caused by size of integer numbers that are limited by available memory - it is like working with big integer numbers.
