python - 使用 python 保存不同的预设

Question

对于我的浓缩咖啡机，我正在使用 PyQt5 在 Python 中编写 GUI。我想保存不同的“配置文件”，我可以根据我使用的 bean 来回忆它们。有一个用 TCL 编写的固件（来自名为“不错的浓缩咖啡机”的机器），它显示了我想要的内容（我将附上 2 张图像和其中一个描述文件的片段，该文件中的第 1 行包含不同的步骤）。

我不确定我应该使用哪个解析器。我显然总是想为相同的参数保存不同的值（在 c 中我会说相同的结构），所以在某种程度上使用像 configparser 这样总是有独立部分的东西感觉不对。

有人可以给我一个提示我应该使用什么库。总是有相同的参数，但不同的配方可能包含不同数量的步骤。

我想要这样的伪代码：

recipe=open('recipe1.txt')
currentstep=0
for steps in recipe:
    pressure = step[currentstep].pressure
    flow = step[currentstep].flow
    ...
    brew()
    currentstep = currentstep + 1

步骤 概述

这是在 TCL 文件中：

The last two steps keep pressure/flow under control as the puck erodes, if the shot has not finished by the end of step 3. Please consider this as a starting point for tweaking.}
