下拉菜单 - 浮点值

Question

我正在尝试使用iPywidgets创建一个下拉列表，它需要返回变量值，此变量值可能会根据其他滑块输入值而更改。当我尝试返回变量时，我会收到错误：nameError：'awadment_one'未定义。

calculated_area = input_slider / numstorey_input_slider * 0.7
revised_area = input_slider - calculated_area
adjustment_one = revised_area / input_slider
    
location = ipywidgets.Dropdown(   
    options=[('Internal', 1), ('Roof', adjustment_one), ('External', 2) ],
    value=1,
    description='Plant Space Location: ',
)

上述方法已解决，是一个缩进的错误，但是我现在发现我无法使用iPyWidget下拉列表传递浮点数。以下是代码 - 基于下拉列表中选择的内容，该代码将映射到数据帧作为乘数。但是，当我打开Excel文档时，它仅返回值'0'。当选择屋顶时，此值实际上应为0.87，并且会根据滑块输入值而更改。

    calculated_roof_area = gia_input_slider / numstoreys_input_slider * 0.7
    revised_gia_roofinput = gia_input_slider - calculated_roof_area
    gia_adjustment_rooftop = revised_gia_roofinput / gia_input_slider
    
    plantspace = ipywidgets.Dropdown(   
    options=[('Internal', 1), ('Roof', gia_adjustment_rooftop), ('External', 2) ],
    value=1,
    description='Plant Space Location: ',
    )
    
    print(plantspace)  
    
    df = pd.read_excel(r'dataframe_final.xlsx', sheet_name='sheet1')
        
    # below recalculates the adjusted qty when the slider position changes
    
    multipliers = {
        'Building Footprint Factor': bldg_footprint_factor,
        'CAT A Fitout Yes / No': fitout_cat_dropdown,
        'GIA Factor': gia_factor,
        'GIA Adjustment - Rooftop': plantspace_dropdown
    }

    df['QP1 Multiplier'] = df['QP1'].map(multipliers)
    df['QP2 Multiplier'] = df['QP2'].map(multipliers)
    df['QP3 Multiplier'] = df['QP3'].map(multipliers)
    df['QP4 Multiplier'] = df['QP4'].map(multipliers)
    df['QP5 Multiplier'] = df['QP5'].map(multipliers)
    df['QP6 Multiplier'] = df['QP6'].map(multipliers)
    df['QP7 Multiplier'] = df['QP7'].map(multipliers)
    df['QP8 Multiplier'] = df['QP8'].map(multipliers)
    df['QP9 Multiplier'] = df['QP9'].map(multipliers)

有人可以帮忙吗？
