python实现进程调度算法代码1、 优先级进程调度算法 2、 时间片轮转进程调度算法

1、优先级进程调度算法的Python实现代码：

class Process:
    def __init__(self, name, priority):
        self.name = name
        self.priority = priority

process_list = [Process('P1', 2), Process('P2', 1), Process('P3', 3), Process('P4', 1)]

def priority_scheduling(process_list):
    process_list.sort(key=lambda x: x.priority, reverse=True)
    for process in process_list:
        print('Running process:', process.name)

priority_scheduling(process_list)

2、时间片轮转进程调度算法的Python实现代码：

class Process:
    def __init__(self, name, burst_time):
        self.name = name
        self.burst_time = burst_time

process_list = [Process('P1', 10), Process('P2', 5), Process('P3', 8)]

def round_robin_scheduling(process_list, time_quantum):
    ready_queue = process_list[:]
    current_time = 0
    while ready_queue:
        process = ready_queue.pop(0)
        if process.burst_time > time_quantum:
            process.burst_time -= time_quantum
            current_time += time_quantum
            ready_queue.append(process)
        else:
            current_time += process.burst_time
            print('Running process:', process.name, 'at', current_time)
    
round_robin_scheduling(process_list, 3)

以上两段代码只是简单的示例，实际应用中还需要考虑进程的状态转换、就绪队列和阻塞队列等问题。
