Having issues with some 'if' statements

[blakefindlay]

The goal here is to have the if statements check the time and date and if those conditions are met I want to subtract $15 off the rental price

def ski_save_click():
    #Setting rental_period as a variable 'days'
    days = rental_period.get()
    price = int(days) * 15 + 10
    save_label = Label(root,
                       text="Saved!"
                       )
    save_label.grid(row=17,
                    column=4
                    )
    save_label.after(3000,
                     save_label.destroy
                     )
    t = datetime.datetime.now().hour
    tmwk = False
    tmwkend = False
    wday = False
    wkend = False
    eligible = False

    if price > 25:
        eligible = True

    if t > 17:
        tmwk = True

    if t > 16:
        tmwkend = True

    if weekday == (["Monday", "Tuesday", "Wednesday", "Thursday", "Friday"]):
        wday = True

    else:
        wkend = True

    if eligible and tmwk and wday:
        int(price - 15)

    else:
        int(price)

    if eligible and tmwkend and wkend:
        int(price - 15)

    else:
        int(price)
