如何从python脚本对C程序进行基准测试？

import subprocess

def compile_c_program(c_file):
    subprocess.run(['gcc', c_file, '-o', 'output'])

import time

def benchmark_c_program():
    start_time = time.time()
    subprocess.run('./output')  # 执行编译后的C程序
    end_time = time.time()
    execution_time = end_time - start_time
    print("C程序执行时间：", execution_time)

import timeit

def benchmark_c_program():
    execution_time = timeit.timeit('subprocess.run("./output")', setup='import subprocess', number=10)
    average_execution_time = execution_time / 10
    print("C程序平均执行时间：", average_execution_time)
