ContextVar.reset()

ContextVar.reset() is a Python method in the ContextVars Module category. Resets the context variable to its previous value using the token from set(). The syntax is ContextVar.reset(token). Returns: None. A typical example: token = user_id.set(42) # ... user_id.reset(token) # Back to previous value. A close sibling is contextvars.ContextVar(), which creates a context variable that has separate values in different async contexts. A close sibling is ContextVar.get(), which returns the value of the context variable for the current context. A close sibling is ContextVar.set(), which sets the value of the context variable for the current context. A close sibling is contextvars.copy_context(), which returns a copy of the current context (all context variables and their values).
