Is there any simple way to benchmark python script?

Usually I use shell command time. My purpose is to test if data is small, medium, large or very large set, how much time and memory usage will be.

Memory Profiler for all your memory needs.

https://pypi.python.org/pypi/memory_profiler

Run a pip install:

pip install memory_profiler

Import the library:

import memory_profiler

Add a decorator to the item you wish to profile:

@profile
def my_func():
    a = [1] * (10 ** 6)
    b = [2] * (2 * 10 ** 7)
    del b
    return a

if __name__ == '__main__':
    my_func()

Execute the code:

python -m memory_profiler example.py

Recieve the output:

 Line #    Mem usage  Increment   Line Contents

 6    166.20 MB  152.59 MB       b = [2] * (2 * 10 ** 7)
 7     13.61 MB -152.59 MB       del b
 8     13.61 MB    0.00 MB       return a
