How to change a variable value depending on the system being used? (Python)

October 13, 2023

E.g. if Windows is used, add this option:

chrome_options.add_argument('user-data-dir=C:\Users\%USERNAME%\AppData\Local\Google\Chrome\User Data\Default)

in case of OS X:

chrome_options.add_argument('user-data-dir=~/Library/Application Support/Google/Chrome/Default')

I could not find any information on this topic. It’s kind of more a question about how usually in development os versions problems are resolved? E.g for GitHub: should I write and push 2 versions of code for each OS?

>Solution :

import platform

system = platform.system()

if system == "Windows":
    chrome_options.add_argument('user-data-dir=C:\Users\%USERNAME%\AppData\Local\Google\Chrome\User Data\Default')
elif system == "Darwin":
    chrome_options.add_argument('user-data-dir=~/Library/Application Support/Google/Chrome/Default')
else:
    raise Exception("Unsupported operating system")
