The chatGPT robot helped me write a program about monitoring the network traffic of the process, and there was always an error

[王尔德（成都市高新区世纪星耀科技工作室）]

No matter how you ask chatGPT to change the error, but this error has always been there, does anyone know why?

所有代码：

import psutil

import time

# 设置监控的进程名称

process_name = "aDrive.exe"

# 上一次检测到进程运行的时间

last_running_time = 0

# 上一次记录的上传下载总流量

last_up_total = 0

last_down_total = 0

# 定义获取进程网络接口的函数

def get_process_nic(process_name):

    for c in psutil.net_connections(kind='inet4'):

        try:

            if c.pid and psutil.Process(c.pid).name() == process_name:

                return psutil.Process(c.pid).io_counters()

        except psutil.NoSuchProcess:

            pass

    return None

# 定义格式化输出函数

def format_output(up_total, down_total, up_speed, down_speed):

    print(f"\rUP_Total: {up_total / 1024:.2f} KB; Down_Total: {down_total / 1024:.2f} KB; UP: {up_speed / 1024:.2f} KB/s; DOWN: {down_speed / 1024:.2f} KB/s", end="")

# 主循环

while True:

    # 获取当前时间

    current_time = time.time()

    # 检查进程是否正在运行

    running = False

    for process in psutil.process_iter():

        if process.name() == process_name:

            running = True

            break

    if running:

        # 如果进程正在运行，获取当前上传下载流量

        process_nic = get_process_nic(process_name)

        if process_nic is None:

            continue  # 如果无法获取进程的网络接口，则跳过

        current_up_total = process_nic.bytes_sent

        current_down_total = process_nic.bytes_recv

        # 如果是第一次检测到进程运行，记录当前的上传下载总流量

        if last_running_time == 0:

            start_up_total = current_up_total

            start_down_total = current_down_total

        # 计算上传下载速度

        up_speed = (current_up_total - last_up_total) / (current_time - last_running_time)

        down_speed = (current_down_total - last_down_total) / (current_time - last_running_time)

        # 更新上一次记录的上传下载总流量和检测到进程运行的时间

        last_up_total = current_up_total

        last_down_total = current_down_total

        last_running_time = current_time

        # 格式化输出

        format_output(current_up_total - start_up_total, current_down_total - start_down_total, up_speed, down_speed)

    else:

        # 如果进程没有运行，显示“wait api” + 时间戳

        print(f"\rwait api {int(current_time)}", end="")

        # 清空记录的上传下载总流量和检测到进程运行的时间

        last_running_time = 0

        last_up_total = 0

        last_down_total = 0

    # 等待2秒钟

    time.sleep(2)
