python比特币工具
bitcoin的Python项目详细描述
#pybitcointools，用于比特币签名和交易的python库
###优点：
- 函数有一个简单的界面，以标准格式输入和输出
- 不上课
- 许多功能都可以单独使用
- 支持二进制、十六进制和base58
- 事务反序列化格式几乎与bitcoinjs兼容
- Electrum和BIP0032支持
- 在一条命令行指令中生成并发布事务
- 包括非比特币特定转换和JSON实用程序
###缺点：
- 不是完整节点，不知道块是什么
- 依赖集中服务（blockchain.info）进行区块链操作，但操作确实有备份（eligius，blockr.io）
###示例用法（最佳学习方法：）：
