Highlighting an excel cell using conditional formatting in python

Question

I'm trying to create a program that reads an excel file containing some data, asks the user for an input, and if the input entered is equal to data within a cell, the cell gets highlighted. This code currently works fine till the user's input is compared with the data.

However I cannot find the correct way to highlight a cell if there is a match with the entered input. What can I do about this? I tried conditional formatting with xlsxwriter but realized while going through documentation that it can only be used to create new files and not change or modify existing files and tried using openpyxl here but to no avail. Sorry I'm just a bit new at this and would really appreciate some help fixing this code

import pandas as pd
import xlsxwriter
from openpyxl import Workbook
from openpyxl.styles import Color, PatternFill, Font, Border
from openpyxl.styles.differential import DifferentialStyle
from openpyxl.formatting.rule import ColorScaleRule, CellIsRule,
FormulaRule

    def checkIfValuesExists1(dfObj, listOfValues):
    ''' Check if given elements exists in dictionary or not'''
    resultDict = {}
    # Iterate over the list of elements one by one
    for elem in listOfValues:
        # Check if the element exists in dataframe values
        if elem in dfObj.values:
            resultDict[elem] = True
        else:
            resultDict[elem] = False
    # Returns a dictionary of values & their existence flag        
    return resultDict

def main():
    import pandas as pd 
    df=pd.read_excel("filename.xlsx") 
    df

    # Create a DataFrame object
    empDfObj = pd.DataFrame(df, columns=['Name', 'LastName', 
    'MiddleName'])

    print('Contents of the dataframe :')
    print(empDfObj)

    print('**** Check if an element exists in DataFrame using in & not in 
   operators ****')

    x= str(input("Enter your text: "))

    print('** Use in operator to check if an element exists in dataframe 
**')

    if x in empDfObj.values:

    df.style.apply(lambda y:['background:red' if x == df.Category else 
    'background:green' for x in df],axis=0)

        print('Element exists in Dataframe')
    else:
        print('Element does not exist in Dataframe')

    # Check if 'Hello' doesn't exist in DataFrame
   # if 'Hello' not in empDfObj.values:
         #print('Element does not exist in Dataframe')

    # Get the xlsxwriter workbook and worksheet objects.
    df.to_excel('output1.xlsx', engine='xlsxwriter')

if __name__ == '__main__':
    main()

要获取单元格的值，您只需要使用.cell并选择行和列即可， .cell回答的那样- 从python中的excelsheet读取特定的单元格值
