python投票系统代码

在Python中实现一个简单的投票系统，通常会涉及数据结构如字典、列表或者集合来存储选票和候选人。下面是一个简化的例子，展示如何创建一个命令行投票程序：

class Election:
    def __init__(self):
        self.votes = {}

    def add_candidate(self, candidate):
        if candidate not in self.votes:
            self.votes[candidate] = 0

    def vote(self, voter, candidate):
        if voter and candidate:
            self.votes[candidate] += 1

    def get_leader(self):
        return max(self.votes, key=self.votes.get)

# 使用示例
election = Election()
election.add_candidate("A")
election.add_candidate("B")
election.add_candidate("C")

voter1 = "Alice"
voter2 = "Bob"

election.vote(voter1, "A")
election.vote(voter2, "B")

print(f"当前领先者: {election.get_leader()} ({election.votes[election.get_leader()]})")
