select_plot() File "select01.py", line 38, in select_plot print("Please select\uff08Input 1-4\uff0c q for exit\uff09\uff1a") UnicodeEncodeError: 'latin-1' codec can't encode character '\uff08' in position 13: ordinal not in range(256)

这个错误是因为在输出字符串时，控制台无法正确地处理某些 Unicode 字符。您可以尝试在代码开头添加一行声明，将默认字符集设置为 UTF-8：

# -*- coding: utf-8 -*-
import pandas as pd
import matplotlib.pyplot as plt
import random

# rest of the code ...

这样做应该会解决该错误。

根据代码提示，Classic_fig未定义，所以我们需要先定义Classic_fig，或者将其从plot_options中删除。下面是两种修改方案：

方案一：定义Classic_fig

可以先定义Classic_fig，例如：

Classic_fig = plt.figure()
# 添加Classic_fig的子图等操作

然后再将Classic_fig添加到plot_options中，如下所示：

plot_options = {
    '1': Classic_fig,
    '2': MassFlowReport_fig,
    '3': Temperature_fig,
    '4': Pressure_food_fig
}

方案二：删除Classic_fig

如果不需要Classic_fig，可以将其从plot_options中删除，如下所示：

plot_options = {
    '2': MassFlowReport_fig,
    '3': Temperature_fig,
    '4': Pressure_food_fig
}

这样就可以避免Classic_fig未定义的错误了。
