写一个用python实现输入任意DFA将其转换为状态转换图并化简DFA输出化简后的状态转换图的完整代码

好的，以下是一个使用 Python 实现输入任意 DFA，将其转换为状态转换图并化简 DFA，最后输出化简后的状态转换图的完整代码：

from graphviz import Digraph

class DFA:
    def __init__(self, states, inputs, start, finals, transitions):
        self.states = states
        self.inputs = inputs
        self.start = start
        self.finals = finals
        self.transitions = transitions

    def minimize(self):
        # 状态合并
        groups = [set(self.finals), set(self.states) - set(self.finals)]
        while True:
            new_groups = []
            for group in groups:
                for inp in self.inputs:
                    next_states = set([self.transitions[(state, inp)] for state in group])
                    for g in groups:
                        if next_states.issubset(g):
                            break
                    else:
                        new_groups.append(next_states)
                        break
                else:
                    new_groups.append(group)
            if len(new_groups) == len(groups):
                break
            groups = new_groups

        # 构造化简后的 DFA
        state_map = {}
        new_states = []
        for i, group in enumerate(groups):
            if self.start in group:
                start = "S{}".format(i)
            new_state = "S{}".format(i)
            new_states.append(new_state)
            for state in group:
                state_map[state] = new_state
        new_finals = set([state_map[final] for final in self.finals])
        new_transitions = {}
        for state in self.states:
            for inp in self.inputs:
                new_transitions[(state_map[state], inp)] = state_map[self.transitions[(state, inp)]]

        return DFA(new_states, self.inputs, start, new_finals, new_transitions)

# 输入 DFA 信息
states = input("请输入状态集合（用空格隔开）：").split()
inputs = input("请输入输入符号集合（用空格隔开）：").split()
start = input("请输入起始状态：")
finals = input("请输入终止状态集合（用空格隔开）：").split()

transitions = {}
for state in states:
    for inp in inputs:
        next_state = input("请输入从状态 {} 经过输入符号 {} 到达的状态：".format(state, inp))
        transitions[(state, inp)] = next_state

# 定义 DFA 对象
dfa = DFA(states, inputs, start, finals, transitions)

# 进行 DFA 化简
dfa_minimized = dfa.minimize()

# 定义状态转换图
dot = Digraph(comment="State Transition Diagram")

# 添加状态节点
for state in dfa_minimized.states:
    if state in dfa_minimized.finals:
        dot.node(state, shape="doublecircle")
    else:
        dot.node(state, shape="circle")
dot.node("start", shape="point")

# 添加状态转换边
dot.edge("start", dfa_minimized.start)
for (state, inp), next_state in dfa_minimized.transitions.items():
    dot.edge(state, next_state, label=inp)

# 保存状态转换图为图片
dot.render("DFA", view=True)

您可以将以上代码复制到 Python 环境中，并按照提示输入 DFA 信息，最后将输出化简后的状态转换图。注意，您需要安装 Graphviz 工具包才能成功运行以上代码。
