Python 3.4+tracemallocfunction

tracemalloc.is_tracing()

tracing control

Returns True if tracemalloc is currently tracing memory allocations.

Syntax

tracemalloc.is_tracing() -> bool

Useful in library code that must neither switch tracing on itself nor break without it: take_snapshot() raises RuntimeError when tracing is off, while get_traced_memory() silently returns (0, 0) — zeros that are easy to read as "memory did not grow". Checking is_tracing() tells "zero" apart from "not measured".

Examples

import tracemalloc
print(tracemalloc.is_tracing())  # → False
print(tracemalloc.get_traced_memory())  # → (0, 0) — не замер, а «не мерили»
tracemalloc.start()
print(tracemalloc.is_tracing())  # → True
tracemalloc.stop()
