如何使用QProcess同时运行多个python脚本

使用QProcess同时运行多个Python脚本可以通过以下步骤实现：

导入必要的模块：

from PyQt5.QtCore import QProcess

创建QProcess对象：

process1 = QProcess()
process2 = QProcess()

定义要运行的Python脚本路径：

script1_path = "/path/to/script1.py"
script2_path = "/path/to/script2.py"

设置要运行的命令行参数（如果有）：

script1_args = ["arg1", "arg2"]
script2_args = ["arg3", "arg4"]

连接QProcess的readyReadStandardOutput信号，以便获取脚本的输出信息：

process1.readyReadStandardOutput.connect(process1_output)
process2.readyReadStandardOutput.connect(process2_output)

def process1_output():
    output = process1.readAllStandardOutput().data().decode()
    print("Script 1 output:", output)

def process2_output():
    output = process2.readAllStandardOutput().data().decode()
    print("Script 2 output:", output)

启动QProcess并运行Python脚本：

process1.start("python", [script1_path] + script1_args)
process2.start("python", [script2_path] + script2_args)

等待脚本运行完成：

process1.waitForFinished()
process2.waitForFinished()

完整的示例代码如下：

from PyQt5.QtCore import QProcess

process1 = QProcess()
process2 = QProcess()

script1_path = "/path/to/script1.py"
script2_path = "/path/to/script2.py"

script1_args = ["arg1", "arg2"]
script2_args = ["arg3", "arg4"]

process1.readyReadStandardOutput.connect(process1_output)
process2.readyReadStandardOutput.connect(process2_output)

def process1_output():
    output = process1.readAllStandardOutput().data().decode()
    print("Script 1 output:", output)

def process2_output():
    output = process2.readAllStandardOutput().data().decode()
    print("Script 2 output:", output)

process1.start("python", [script1_path] + script1_args)
process2.start("python", [script2_path] + script2_args)

process1.waitForFinished()
process2.waitForFinished()

这样，你就可以同时运行多个Python脚本，并获取它们的输出信息。
