liunx下获取指定python脚本进程正在运行的线程数量

简单封装了段Python代码可在liunx下查看指定python脚本运行的线程数量：

import os
 
'''
@:param script_name 脚本名称 示例：run_api.py
'''
def get_process_threads_num(script_name):
    process_text = os.popen(f"ps -ef |grep {script_name}").read()
    print(process_text.split("\n")[0])
    process_pid = None
    for text in process_text.split("\n"):
        if f"python {script_name}" in text:
            process_pid = [x for x in text.split(" ") if x][1]
    print("进程pid：", process_pid)
    if process_pid:
        threads_text = os.popen(f'cat /proc/{process_pid}/status |grep Threads').read()
        print("线程数信息：\n", threads_text)
        return threads_text.split("\t")
    else:
        return None
 
 
print("线程数：", get_process_threads_num("run_api.py"))
 
'''
cat /proc/{process_pid}/status |grep Threads
'''
