Using loop on a list to creat another list from it. but it is printing an empty list

Question

why my code is always printing empty list_of_lists ?? There is nothing wrong with the class and all functions is well implemented

I think that the problem is the way i am using the loop but i can not discover ... What i should do to fix this? as you see i am still beginner

Note: i did not add the Class and the functions here not to be long code.

print("Consider this format=> normal: 20Mar2009(fri), 21Mar2009(sat), 22Mar2009(sun)")

info = input("")

client_type = get_client_type(info)      #function that return client type 

given_dates = get_given_dates(info)      #function that return a list with several dates

day_type = get_day_type(info)  #function that process the given date and return "workday" or "holiday"

days_num = len(given_dates)

list_of_lists = []

for date in given_dates:
    
    if day_type == "holiday" and client_type == "normal":                        
        list1=[]    
        list1.append(Hotel.normal_holiday(hotel1)) #Refere to the class Hotel created before
        list1.append(Hotel.normal_holiday(hotel2))        
        list1.append(Hotel.normal_holiday(hotel3))
        list1 = list(map(int, list1))               
        list_of_lists.append(list1)
        print(list_of_lists)
    
    elif day_type == "workday" and client_type == "normal":
        pass
