i have a programm that generate the list and then i ask them to tell me what they want to do from the menu and this is where my problem start i was able to get the input form the user to different function but when i try to use the if else condition it doesn't check, below are my code

def menu(x,l):
    print (x)
    if x == 1:
        return make_table(l)
    if x == 2:
        y= input("enter a row (as a number) or a column (as an uppercase letter")
        if y in [ "1",'2','3']:
            print("Minmum is:",minimum(y,l))
    if x== 3:
        print ('bye')

def main():
    bad_filename = True
    l =[]
    while bad_filename == True:
        try:
            filename = input("Enter the filename: ")
            fp = open(filename, "r")
            for f_line in fp:
                f_str=f_line.strip()
                f_str=f_str.split(',')
                for unit_str in f_str:
                    unit=float(unit_str)
                    l.append(unit)
            bad_filename = False
        except IOError:
            print("Error: The file was not found: ", filename)
        #print(l)
    condition=True

    while condition==True:
        print('1- open\n','2- maximum')
        x=input("Enter the choice")
        menu(x,l)

main()

from the bottom function i can get list and i can get the user input and i can get the data and move it in second function but it wont work after that.thank you
