unexpected object?

[snippsat]

Will be trouble if try to generate new file in each loop.
So have the making of file object outside of the loop,then write to file in the loop.

file_name = "temp.txt"
with open(file_name, "a") as file:
    while True:
        name = input("Your name, again:")
        if name == "":
            break
        else:
            file.write(f'{name}\n')
