最全面的比特币Python库是 Vitalik Buterin写的 pybitcointools。在例4-5中，我们使用pybitcointools库（导入 为“bitcoin”）来生成和显示不同格式的密钥和比特币地址。

例4-5 使用pybitcointools库的密钥和比特币地址的生成和格式化

例4-6是上例代码运行输出的内容。

例4-6 运行key-to-address-ecc-example.py

$ python key-to-address-ecc-example.py

例4-7是另外一个示例，使用的是Python ECDSA库来做椭圆曲线计算而非bitcoin的库。

例4-7 用于比特币密钥的椭圆曲线算法演示脚本

link:code/ec-math.py[]

例4-8是上述脚本的输出。

警告：例4-7中使用的os.urandom，表明的是底层操作系统的加密安全随机数生成器（cryptographically secure random number generator (CSRNG) ）。注意：根据操作系统的不同，os.urandom的实现缺乏足够的安全性，也可能没有正确的种子，并且不适合产生高质量的比特币密钥。

例4-8 安装Python ECDSA 库，运行脚本running the ec_math.py

$ # Install Python PIP package manager
$ sudo apt-get install python-pip
$ # Install the Python ECDSA library
$ sudo pip install ecdsa
$ # Run the script
$ python ec-math.py
