Python：将多个参数附加到元组

Question

I'd like to append multiple arguments to the tuple, but I don't know how

Here's my dict() :

OBJECTS = { item1 : 'None', item2 : 'None' }

CODE:

def a(file):
    fp = open(file, 'Ur')
    data_list = []
    for line in fp:
        data_list.append(tuple(line.strip().split('|')),OBJECTS)
    fp.close()
    return data_list

And Python return Error:

TypeError: append() takes exactly one argument (2 given)

Answer 1

You can use the + operator to concatenate collections:

[1, 2, 3] + [4, 5, 6]

(1, 2, 3) + (4, 5, 6)

Answer 2

As the error states, you can only append one item to the list at a time.

So, you want to call append twice:

data_list.append(tuple(line.strip().split('|')))
data_list.append(OBJECTS)

However, I'm not sure if you want to actually append OBJECTS to the array for each line, considering that OBJECTS is not dependent on the line.
