Pandas 更改单元格颜色

Pandas change cell color

如果单元格包含字符串列表中的字符串,我将尝试更改单元格颜色:

这允许我在有匹配项时更改颜色,但它似乎没有遍历列表中的每个项目它只匹配第一个(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

我正在尝试以下方法,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

我调用这些函数如下:

s = df1.style.applymap(color_negative_blue)

我希望能够遍历项目列表,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

Acquire               Infrastructure        Botnet      Drive-by Compromise 
DNS Server                                               Exploit Public-Facing Application  
Domains                                                 External Remote Services    
Server                                                  Hardware Additions  
Virtual Private Server                    Phishing      Spearphishing Attachment
Web Services                              Spearphishing Link
Compromise Accounts Email Accounts                      Spearphishing via Service
Social Media Accounts                                   Replication Through Removable Media 


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

当内容匹配时替换任何单元格 techniques:

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

df.style.applymap(my_func_blue).render()
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匹配的单元格的颜色
