How to iterate over a list of list using 'in' operator

Question

I have a list of lists (path_list; actually this is a path object) and another list (y_path).

Now, I want to remove and filter those two lists based on another list remove_all_list.

The remove function (not in) is working fine. But, when I am using the in function I am getting an empty list.

Code is given below

remove_all_list = ["Image_034_S_0735_Img_Na__Ma_F_", "Image_033_S_0733_Img_Na__Ma_F_"]

X_test = path_list.copy()
y_test = y_path.copy()

for remove_item in remove_all_list:
    path_list = [[item for item in sub_list if remove_item not in item.name] for sub_list in path_list]
    y_path = [item for item in y_path if remove_item not in item.name]
    X_test = [[item for item in sub_list if remove_item in item.name] for sub_list in X_test]
    y_test = [item for item in y_test if remove_item in item.name]

X_train_val = [x for x in path_list if x] # Removing empty list
X_test_all = [x for x in X_test if x] # Removing empty list

The shape I am getting from the loop

print(np.shape(y_path), np.shape(X_train_val), np.shape(y_test), np.shape(X_test_all))

(2,) (2, 2) (0,) (0,)

But, the expected shape is (2,) (2, 2) (2,) (2, 2). Any ideas are appreciated.
