Basically, os.environ is found on import, and os.geten v is a wrapper to os. environ.get, at least in CPython. EDIT: To respond to a comment, in CPython, os.getenv is basically a shortcut to os.environ.get since os.environ is loaded at import of os, and only then, the same holds for os.getenv.
While there is no functional difference between os. environ.get and os.getenv, there is a massive difference between os.putenv and setting entries on os.environ.os.putenv is broken, so you should default to os. environ.get simply to avoid the way os.getenv encourages you to use os.putenv for symmetry.. os.putenv changes the actual OS-level environment variables, but in a way that doesn’t show up …

Basicamente, os.environ é encontrado na importação e os.getenv é um wrapper para os.environ.get, pelo menos no CPython. EDIT: Responder a um comentário, no CPython, os.getenv é basicamente um atalho para os.environ.get desde que os.environ é carregado na importação de os, e somente então, o mesmo vale para os.getenv.
Fondamentalmente, os.environ si trova durante l’importazione e os.getenv è un wrapper per os. environ.get , almeno in CPython. EDIT: per rispondere a un commento, in CPython, os.getenv è fondamentalmente una scorciatoia per os. environ.get da os.environ viene caricato all’importazione di ose solo allora lo stesso vale per os.getenv.
Hoewel er geen functioneel verschil is tussen os. environ.get en os.getenv, er is een enorm verschil tussen os.putenv en het instellen van items os.environ. os.putenv is gebroken, dus u moet standaard naar os. environ.get gewoon om de weg te vermijden os.getenv moedigt u aan om te gebruiken os.putenv voor symmetrie.
