Code error (Python, Pandas and Excel)

Question

I made a code to pick the time and day of the week and so picks up the cell of the excel spreadsheet and should inform me, but it is going wrong when picking up, besides on Tuesday (incicaçao ES) gives error.

An example of error is: today is Wednesday 12:53, it was supposed to be lunch but he says the value is "study history".

Column and row variable is giving the right value.

import pandas as pd #importa para mecher no excel
from datetime import date #importa semna
from datetime import datetime #importa data

for nu in range(10000000000): #repete
    print("---------------------------------------------------------------------------------------") #separa só estetico
    hj = date.today() #pega o dia de hoje
    dias = ('Segunda-feira', 'Terça-feira', 'Quarta-feira', 'Quinta-feira', 'Sexta-feira', 'Sábado', 'Domingo') #lista dos dias
    print ("Hoje é", dias[hj.weekday()]) #fala que dia da semana é
    x = pd.read_excel(r"C:\Users\Victor\Desktop\rotina p.xlsx") #le a planilha
    semana = dias[hj.weekday()]  #Salva que dia da semana é

    minuto = datetime.today().minute #pega o minuto
    hora = datetime.today().hour #pega a hora

    #SE o dia for tal ele poe o nome da prmeira linha para pega a coluna
    if(semana == 'Segunda-feira'): 
        su = "AS"
    elif(semana == 'Terça-feira'):
       su = "ES"
    elif(semana == 'Quarta-feira'):
       su = "IS"
    elif(semana == 'Quinta-feira'):

    #Ve se é antes ou depois de 30 minutos
    if(minuto >= 0 and minuto <= 30):
