Identify the platform running Python (Kaggle / Colab / Windows)

Purpose

In competitions, etc., the file reading process and import module will change between local and cloud, so it will be possible to switch automatically. Kaggle, Google Colaboratory, Local (Windows 10)

Execution environment (as of March 15, 2020)

• Windows 10 Home(64bit)
• kaggle
• google Colaboratory

Overview / Method

Discrimination method,

1. Local (Windows) and cloud judgment are judged from the OS with os.name
2. Kaggle / Colab is judged by the presence or absence of Kaggle's unique environment variable'KAGGLE_DATA_PROXY_TOKEN'

Please let me know if there is a smarter judgment method.

Processing content of each platform

• Windows: --Read from local folder --Japanese setting of matplotlib
• Kaggle: --Read from kaggle cloud folder
• Google Colaboratory: --Read from Google Drive --Display session time (check remaining time)

Discrimination

import os

# windows
if os.name == 'nt':
    path = '../input/data/'

    import japanize_matplotlib
    sns.set(font="IPAexGothic")

elif os.name == 'posix':
# Kaggle
    if 'KAGGLE_DATA_PROXY_TOKEN' in os.environ.keys():
        path = '/kaggle/input/'

# Google Colab
    else:
        from google.colab import drive
        drive.mount('/content/drive')
        !ls drive/My\ Drive/'Colab Notebooks'/xxx #xxx rewrite
        path = "./drive/My Drive/Colab Notebooks/xxx/input/data/" #xxx rewrite
        #Check the remaining time of the session
        !cat /proc/uptime | awk '{print $1 /60 /60 /24 "days (" $1 / 60 / 60 "h)"}'

print(os.name)
print(path)
