如果单元格包含字符串列表中的字符串,我正在尝试更改单元格颜色:

这允许我在匹配时更改颜色,但它似乎不会遍历列表中的每个项目,它只进行第一个匹配(我认为这是因为 ==)

def color_negative_red(val):
    for technique in techniques:
        color = 'green' if val == technique else 'black'
        return 'color: %s' % color

我正在尝试以下操作,但似乎没有改变任何颜色:

def color_negative_blue(val):
    for technique in techniques:
        color = 'blue' if technique in val else 'black'
        return 'color: %s' % color

我这样称呼这些函数:

s = df1.style.applymap(color_negative_blue)

我希望能够查看项目列表,如果列表中的项目存在,则更改单元格中该文本的颜色。

数据帧:

Column1                Column2              Column3          Column4

techniques = ['Server','Web Services', 'Phishing']

当其内容匹配techniques时替换任何单元格:

def my_func_blue(val):
   if val in techniques:
      return "color: blue"
   else:
      return "color: black"

df.style.applymap(my_func_blue).render()

答案 1 :(得分:0)

def my_func_blue(val):
    if val in techniques:
        color = 'green'
        return f'background-color: {color}'
    else:
        color = 'red'
        return f'background-color: {color}'

上面的代码允许我执行搜索并更改它匹配的单元格的颜色
