For vs Join comparation in python.

Comparation between "for" and "join" in python, testing which version is more efficient.

Requirements

• python >= 3.6
• memory-profiler == 0.57.0

Installation

In this section installation using virtualenv for linux will be explained. You must install virtualenv if you have not, you can follow the installation guide.

Once you have virtualenv installed, open the terminal in project's directory and write the following command in terminal

virtualenv .venv -p $(which python3)

To activate the virtualenv:

source .venv/bin/activate

Once we have our virtualenv activated, we can install the requirements.

pip install -r requirements.txt

Now you can run the test with:

python3 code/tests.py

Tests

In this tests, memory and executing time have being measured in order to obtain which of the two versions, 'for' or 'join', is more efficient.

Tested arrays will have a changing number of strings, depending on the case.

Case 1 (Array with 10 elements)

Case 2 (Array with 1000 elements)

Case 3 (Array with 100000 elements)

Case 4 (Array with 1000000 elements)
