LOLCatFactory

This is a small program to download random LOLCat pictures

Program internals

The program consists of two pieces. Program.py and cat_service.py. The first contains the main functions and the latter contains the code related to downloading the LOLCats

The code for program.py:

__author__ = "byteme8bit"
import os
import cat_service
import subprocess
import platform


def main():
    print_header()

    folder = get_or_create_output_folder()
    print('Found or created folder: ' + folder)

    download_cats(folder)
    display_cats(folder)


def print_header():
    print('--------------------------------------')
    print('                LOL CATS              ')
    print('--------------------------------------')
    print()


def get_or_create_output_folder():
    base_folder = os.path.dirname(__file__)
    # print(base_folder)
    folder = 'cats_pictures'
    full_path = os.path.join(base_folder, folder)
    print(full_path)

    if not os.path.exists(full_path) or not os.path.isdir(full_path):
        print('Creating new directory at {}'.format(full_path))
        os.mkdir(full_path)

    return full_path


def download_cats(folder):
    print('Contacting server to download cats...')
    cat_count = 8
    for i in range(1, cat_count + 1):
        name = 'lolcat_{}'.format(format(i))
        print('Downloading cat ' + name)
        cat_service.get_cat(folder, name)
    print('Done.')


def display_cats(folder):
    print('Displaying cats in OS window...')
    if platform.system() == 'Darwin':
        subprocess.call(['open', folder])
    elif platform.system() == 'Windows':
        subprocess.call(['explorer', folder])
    elif platform.system() == 'Linux':
        subprocess.call(['xdg-open', folder])
    else:
        print("We don't support your OS: " + platform.system())


if __name__ == '__main__':
    main()

The code for cat_service.py:

__author__ = "byteme8bit"
import os
import shutil
import requests


def get_cat(folder, name):
    url = 'http://consuming-python-services-api.azurewebsites.net/cats/random'
    data = get_data_from_url(url)
    save_image(folder, name, data)


def get_data_from_url(url):
    response = requests.get(url, stream=True)
    return response.raw


def save_image(folder, name, data):
    filename = os.path.join(folder, name + '.jpg')
    with open(filename, 'wb') as fout:
        shutil.copyfileobj(data, fout)
