How to measure function memory with sys.getsizeof in Python
Measure the memory footprint of Python functions (user-defined and built-in) using sys.getsizeof.
import sys
def sample_function(a, b, c):
return a + b - c
def measure_function_memory(func):
size = sys.getsizeof(func)
print(f"Memory size of {func.__name__}: {size} bytes")
if __name__ == "__main__":
measure_function_memory(sample_function)
measure_function_memory(print)
measure_function_m…
