动态改变背景颜色，而不是使用静态值

Question

def raw_dp(value, loop_name, break_point_1, break_point_2, break_point_3, break_point_4, break_point_5, metrics, symbol = ''):

    facts = [(round(item)) for item in value]
    metrics  += '''<tr><th>'''+ loop_name +'''</th>'''
    for dp in facts:
        if dp <= break_point_1:
            metrics += '<td style = "background-color:#229954">' + ' ' +  str(dp)  + symbol + '</td>'
        elif dp > break_point_1 and dp <= break_point_2:
            metrics += '<td style = "background-color:#ABC878">' + ' ' +  str(dp)  + symbol + '</td>'
        elif dp > break_point_2 and dp <= break_point_3:
            metrics += '<td style = "background-color:#F9E79F">' + ' ' +  str(dp)  + symbol + '</td>'
        elif dp > break_point_3 and dp <= break_point_4:
            metrics += '<td style = "background-color:#FBD567">' + ' ' +  str(dp)  + symbol + '</td>'
        elif dp > break_point_4 and dp <=break_point_5:
            metrics += '<td style = "background-color:#F9C169">' + ' ' +  str(dp)  + symbol + '</td>'
        else:
            metrics += '<td style = "background-color:#E67C73">' + ' ' +  str(dp)  + symbol + '</td>'
    metrics += '''</tr>'''
    return metrics

我想动态更改 html 单元格的背景颜色，而不是使用我定义为 breakpoint_1、breakpoint_2...等的静态值或任何其他优雅地编写此函数的方式。我是python新手，谁能帮帮我。

Answer 1

我不做 Python，但我建议实现一个案例

https://jaxenter.com/implement-switch-case-statement-python-138315.html

def switch_demo(argument):
  switcher = {
    0: "229954",
    1: "229954",
    2: "ABC878",
    3: "F9E79F",
    4: "FBD567",
    5: "F9C169"
  }

使用类似的东西

bg = switcher.get(argument,"E67C73")

这里你需要将测试变成一个从 0 到 5 的数字——正如我所说的我不会使用 Python，但字典应该是一个可能的解决方案

如果不行，那就试试

                                                   bg = "E67C73"
 if   dp <= break_point_1:                         bg = "229954"
 elif dp >  break_point_1 and dp <= break_point_2: bg = "ABC878"
 elif dp >  break_point_2 and dp <= break_point_3: bg = "F9E79F"
 elif dp >  break_point_3 and dp <= break_point_4: bg = "FBD567"
 elif dp >  break_point_4 and dp <= break_point_5: bg = "F9C169"

然后有一个

metrics += '<td style = "background-color:#' + bg + '">' +  str(dp)  + symbol + '</td>'
metrics += '''</tr>'''

不需要+ ' '，因为在 HTML 中被忽略了。而是设置单元格填充
