Sweep: write mandelbrot/Simple in Python

[leon0399]

Details

Implement mandelbrot/Simple benchmark in Python, and put it into python/mandelbrot/Simple.py.

You MUST implement it exactly in the same way as in other languages examples: php/mandelbrot/Simple.php, javascript/mandelbrot/Simple.js, ruby/mandelbrot/Simple.rb. Add script to python/benchmark.yaml

Here are other examples of out Python code: python/primes/Atkin.py. Use it to se how collect and report execution time.

Step 2: ⌨️ Coding

• Create python/mandelbrot/Simple.py ✓ 5bbec68 Edit

Create python/mandelbrot/Simple.py with contents:
• Begin by importing the necessary modules at the top of the file: `import time`.
• Define the `mandelbrot` function that takes `x` and `y` as parameters. This function should replicate the logic found in the snippets from PHP, JavaScript, and Ruby, adapted to Python's syntax. Use a while loop to iterate until the conditions are met, and return the iteration count or 0 based on the conditions specified in the snippets.
• Define the `index` function that contains two nested for loops to iterate over a range of x and y values, calling the `mandelbrot` function for each pair of coordinates. Print "*" or a space based on the return value of the `mandelbrot` function, similar to the logic in the provided snippets.
• At the bottom of the file, add a script execution block that measures the execution time of the `index` function. Use `time.time()` to get the current time in seconds at the start and end of the execution, calculate the duration, and print it.
• Ensure that the script follows Python's best practices for readability and efficiency.

Modify python/benchmark.yml with contents:
• After the line mentioning `- primes/Simple.py`, add a new line to include the Mandelbrot benchmark script in the benchmark suite: `- mandelbrot/Simple.py`.
• This modification registers the new Python implementation of the Mandelbrot benchmark, allowing it to be executed as part of the suite's benchmarks.
