用Pandas在excel中给细胞着色

Question

我需要帮助。所以我有这样的东西

import pandas as pd
path = '/Users/arronteb/Desktop/excel/ejemplo.xlsx'
xlsx = pd.ExcelFile(path)
df = pd.read_excel(xlsx,'Sheet1')
df['is_duplicated'] = df.duplicated('#CSR')
df_nodup = df.loc[df['is_duplicated'] == False]
df_nodup.to_excel('ejemplo.xlsx', encoding='utf-8')

所以基本上，这个程序将ejemplo.xlsx（ejemplo在西班牙语中是一个例子，只是文件名）加载到df（aDataFrame）中，然后检查特定列中的重复值。它删除重复项并再次保存文件。那部分工作正常。问题是，我需要用不同颜色（如黄色）突出显示包含重复项的单元格，而不是删除重复项。

Answer 1

你可以创建一个函数来突出显示。。。

def highlight_cells():
    # provide your criteria for highlighting the cells here
    return ['background-color: yellow']

然后将突出显示功能应用到数据帧。。。

df.style.apply(highlight_cells)

Answer 2

我刚遇到同样的问题，这周我刚解决了。我的问题是不能让includes正常工作来获取我发现正常工作的在线代码。

我假设你的意思是改变背景颜色而不是改变字体颜色。如果我错了，请澄清你的要求。

我的解决方案与特定的库绑定。打开PYXL

#### This import section is where my mistake was at
#### This works for me
import openpyxl    ### Excel files 
from openpyxl.styles import PatternFill, Border, Side, Alignment, Protection, Font
from openpyxl.styles import Fill, Color
from openpyxl.styles import Style
from openpyxl.styles.colors import RED
from openpyxl.styles.colors import GREEN


str_xls_PathFileCurrent = str_xls_FileName
### Opens Excel Document
var_xls_FileOpen    = openpyxl.load_workbook(str_xls_PathFileCurrent) 
### Opens up the Excel worksheet 
var_xls_TabName     = var_xls_FileOpen.worksheets[0]                  
### Put the spreadsheet tab names into an array 
ary_xls_SheetNames  = var_xls_FileOpen.get_sheet_names()              
### Open the sheet in the file you working on 
var_xls_TabSheet    = var_xls_FileOpen.get_sheet_by_name(ary_xls_SheetNames[0])
xls_cell = var_xls_TabSheet['d10']

#### Changes the cell background color 
xls_cell.style = Style(fill=PatternFill(patternType='solid'
    , fgColor=Color('C4C4C4')))  ### Changes background color 

#### Changes the fonts (does not use style) 
xls_cell.font = xls_cell.font.copy(color  = 'FFFF0000') ### Works (Changes to red font text) 
xls_cell.font = xls_cell.font.copy(bold  = True) ### Works (Changes to bold font) 
xls_cell.font = xls_cell.font.copy(italic= True) ### Works (Changes to Italic Text) 
xls_cell.font = xls_cell.font.copy(size  =   34) ### Works (Changes Size)
