Question

我写了一条条件声明，将房价转换为幅度。但是，当我绘制一个堆叠的条形图以按年份显示房屋价格时，会得到一个专门针对价格为0美元的房屋的条形图。我希望这些房屋属于0- $ 200k的类别

conditions = [
    (housing_data['sale_price'] < 200000) | (housing_data['sale_price']==0),
    (housing_data['sale_price'] > 200000) & (housing_data['sale_price'] < 400000),
    (housing_data['sale_price'] > 400000) & (housing_data['sale_price'] < 600000),
    (housing_data['sale_price'] > 600000) & (housing_data['sale_price'] < 800000),
    (housing_data['sale_price'] > 800000) & (housing_data['sale_price'] < 1000000),
    (housing_data['sale_price'] > 1000000) & (housing_data['sale_price'] < 10000000),
    (housing_data['sale_price'] > 10000000) & (housing_data['sale_price'] < 100000000),
]
choices =['$0-$200k','$200k-$400k','$400k-$600k','$600k-$800k','$800k-$1mlln','$1mlln-$10mlln','$10mlln-$100mlln']
housing_data['price_range'] = np.select(conditions,choices)
ax = housing_data.groupby(['year_of_sale','price_range']).size().unstack().plot.bar(stacked=True)
horiz_offset = 1
vert_offset = 1
ax.legend(bbox_to_anchor=(horiz_offset, vert_offset))

这是我的数据样本

Answer 1

使用cut

进行检查

bins=[-100000000,20000,40000,60000,80000,100000,1000000,10000000]
housing_data['price_range']=pd.cut(housing_data['sale_price'],bins=bins,labels=choices )

条件语句未考虑值为0的行
