Am I dumb?

[aidh18]

I am relatively new to python, and I thought I understood the basics of it already, but for some reason, this one block of code is giving me so many problems. I cannot find the problem with this code, as it just keeps looping for seemingly no reason. What am I doing wrong here? I know this code can be optimized by the way, it was optimized but after it kept looping I thought I would take it back to the basics and that would fix it, but I was wrong.

user_choice = ""
run_loop = "run"

while run_loop == "run":
    print()
    
    if user_choice.lower == "option 1":
        run_loop = "off"
    elif user_choice.lower == "option 2":
        run_loop = "off"
    elif user_choice.lower == "option 3":
        run_loop = "off"
    elif user_choice.lower == "option 4":
        run_loop = "off"
    elif user_choice.lower == "option 5":
        run_loop = "off"
    else:
        print("Here are your options:")
        user_choice = input("Option 1, Option 2, Option 3, Option 4, or Option 5: ")
