python 小程序的脚本可以直接在shell(命令行)解释器里运行:
1. open anaconda powershell window
2. PS > cd d:\algolab
3. 在powershell命令行解释器里运行脚本:
PS > python tcalc.py
3a. 或者在python解释器里运行脚本:
PS > python
>>> import tcalc as cbc
>>> cbc.CBondTransaction().trade()
4. enter 4 'input' by the prompt:
可转债6位代码, 买入量(张数), 买入价, 卖出价
code
volume, buy_price
sell_price
5. Result will be displayed like below!!!
