在python中运行子进程，两者都会“实时”显示输出并将其保存到变量中

import subprocess

def run_command(command):
    process = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True)
    output = ""
    while True:
        line = process.stdout.readline().decode("utf-8")
        if line == '' and process.poll() is not None:
            break
        output += line
        print(line.strip())  # 实时显示输出
    return output

command = "your_command_here"
output = run_command(command)
print("Output:", output)  # 将输出保存到变量中
