Xample

Test your python script against the sample inputs and outputs for the Prologin problems.

Getting Started

Prerequisites

Check if you have python >= 3.6 installed:

python --version  # Python 3.6.X
# python3 --version

If not, download the latest version at https://www.python.org/downloads/

Clone this repository:

# cd to desired location
git clone https://github.com/Pyxidatol-C/Xample

Install the dependencies:

pip install -r requirements.txt 
# pip3 install -r requirements.txt

Quick Start

Let's take a simple example: you are trying to solve this lvl 0 problem.

In exo_42.py (you can choose any filename), write your solution:

# https://prologin.org/train/2017/semifinal/42
input()  # optional
print(42)

Then

cd PATH/TO/CURRENT/DIRECTORY
python xample.py exo_42.py
# python3 xample.py exo_42.py

xample.py and exo_42.py can be in different directories, and you can point to either using absolute or relative paths.

The output (it might take a while to load the samples from the url):

exo_42.py
✅ Found url: https://prologin.org/train/2017/semifinal/42
⚠️ Cannot read samples.json; the file is reinitialized.
✅ Wrote samples to samples.json
✅ Saved url: https://prologin.org/train/2017/semifinal/42
--

✅ Passed

Now let us see what will happen when we (deliberately) make a "mistake":

# https://prologin.org/train/2017/semifinal/42
input()  # optional
print(6 * 9)

Output:

exo_42.py
✅ Found url: https://prologin.org/train/2017/semifinal/42
⚠️ Reading examples from samples.json; delete entry in samples.json to reload.
--

❌ Failed
#Input
QUEL EST LE PRODUIT DE SIX PAR NEUF
#Expected Output
42
#Output
54
#Error

Offline Usage

If samples.json was already populated, xample.py will automatically use the data there instead of redownloading, which allows offline use.

Samples Syntax

samples.json:

{
    "https://prologin.org/train/2017/semifinal/42": [
        {
            "in": "QUEL EST LE PRODUIT DE SIX PAR NEUF\n",
            "out": "42\n"
        }
    ]
}

Note:

• the \n character at the end is kept (used as the input terminator)
