# Biến môi trường (Environment Variables)

/// tip

Nếu bạn đã biết về "biến môi trường" và cách sử dụng chúng, bạn có thể bỏ qua phần này.

///

Một biến môi trường (còn được gọi là "**env var**") là một biến mà tồn tại **bên ngoài** đoạn mã Python, ở trong **hệ điều hành**, và có thể được đọc bởi đoạn mã Python của bạn (hoặc bởi các chương trình khác).

    // my best guess is that the jdk authors have spent more time optimizing that callpath than this
    // one. (StringCoding$StringDecoder vs. StreamDecoder).  StringCoding has a ton of special cases
    // theoretically we could duplicate all that logic here to try to beat 'new String' or at least
    // come close.
