Why this code shows error??

I fully understand the code, I understand what this code is doing and I even gave the right answer, but I just wanted to try it on my own. I don't know why I'm getting a TypeError even when pasting the exact code. Can someone help me with this please? I'll be highly obliged! Thanks in advance!! Here's the Error: TypeError: argument of type 'builtin_function_or_method' is not iterable

I tried this, and it gives me no error. Can you paste your code here? I need to see your code.

all_restaurants = [
    "Taco City",
    "Burgertown",
    "Tacovilla",
    "Hotdog station",
    "House of tacos",
    ]

def tacos_only(restaurants): 
    taco_joints = restaurants.copy()
    for taco_joint in taco_joints.copy():
        if "taco" not in taco_joint.lower:
            taco_joints.remove(taco_joint)
    return taco_joints  

dinner_options = tacos_only(all_restaurants)

print(dinner_options)

I think, I found my mistake. But thank you for your help. You made me to go through the code once again and I found that I typed .lower instead of lower(). Thank you so much, You did my help anyways!😂️
