Pythons "reflection" assistance makes it achievable to get a item that is definitely effective at reassigning a name/variable in a very specified scope without defining functions explicitly in that scope:
Python works by using dynamic typing, and a combination of reference counting in addition to a cycle-detecting rubbish collector for memory management. Additionally, it capabilities dynamic identify resolution (late binding), which binds approach and variable names through method execution.

An important limitation of CPython is the usage of a world interpreter lock (GIL) on Every CPython interpreter procedure, which successfully disables concurrent Python threads in just one process.[one] Concurrency can only be achieved with independent CPython interpreter processes managed by a multitasking operating program. This complicates interaction among concurrent Python processes, however the multiprocessing module mitigates this to some degree.
