এনভায়রনমেন্ট ভেরিয়েবল (সংক্ষেপে "**env var**" নামেও পরিচিত) হলো এমন একটি ভেরিয়েবল যা পাইথন কোডের **বাইরে**, **অপারেটিং সিস্টেমে** থাকে এবং আপনার পাইথন কোড (বা অন্যান্য প্রোগ্রাম) দ্বারা যাকে রিড করা যায়।

এনভায়রনমেন্ট ভেরিয়েবলস অ্যাপ্লিকেশনের **সেটিংস** পরিচালনা করতে, পাইথনের **ইনস্টলেশন** প্রক্রিয়ার অংশ হিসেবে, ইত্যাদি কাজে উপযোগী হতে পারে।

## Env Vars তৈরী এবং ব্যবহার

`**second_user_data` şu anlama geliyor:

Key-Value çiftini direkt olarak  `second_user_data` dictionarysine kaydet , yaptığın şey buna eşit olacak: `User(id=4, name="Mary", joined="2018-11-30")`
