代码管理工具如何创建

import os
import shutil
import datetime

class SimpleVersionControl:
    def __init__(self, repo_path):
        self.repo_path = repo_path
        if not os.path.exists(repo_path):
            os.makedirs(repo_path)
        self.commits = []

    def commit(self, message):
        timestamp = datetime.datetime.now().strftime("%Y%m%d%H%M%S")
        commit_dir = os.path.join(self.repo_path, f"commit_{timestamp}")
        shutil.copytree(self.repo_path, commit_dir, dirs_exist_ok=True)
        self.commits.append((timestamp, message))

    def list_commits(self):
        for commit in self.commits:
            print(f"{commit[0]}: {commit[1]}")

# 使用示例
vc = SimpleVersionControl("my_repo")
vc.commit("Initial commit")
vc.commit("Added new feature")
vc.list_commits()
