What methods can be used to determine how effectively a program or a piece of code is working?

Several methods are used to evaluate the effectiveness of a program or code:

• Profiling — measuring the execution time of functions and resource usage (CPU, memory). In Python, you can use the cProfile module:

import cProfile

def my_function():
    # code
    pass

cProfile.run('my_function()')

• Timing — measuring the execution time of a specific code segment using the time or timeit module:

import time
start = time.time()
# code
end = time.time()
print(f"Execution time: {end - start} seconds")

• Memory usage analysis — using libraries like memory_profiler or tracemalloc.

• Logging and monitoring — collecting metrics in real-time to assess performance in production.

These methods help identify bottlenecks and optimize code.
