When Defining a Function with an Equation as a Default Argument, which Value Is Used?

[DeaD_EyE]

I refactored the code a litte bit.
Test it if it works as expected. Look at the differences.
Have no time to check it for myself.

my_dict = {}
default_sizes = [300, 100]
 
 
def create(text="Default Text", x=None, y=None):
    local_dict = {}
    
    if x is None:
        local_dict["x_position"] = default_sizes[0]
    else:
        local_dict["x_position"] = x
    if y is None:
        local_dict["y_position"] = default_sizes[1] + len(my_dict)
    else:
        local_dict["y_position"] = y
    
    return local_dict


for idx in range(10):
    my_dict[idx] = create()


print(my_dict)
