How to write the return in multiple lines-CodePudding

The following function has many items in the returned tuples:

def test_real():
    return (item_a_long_name, item_b_long_name), (item_c_long_name, item_d_long_name), ..., (item_x_long_name, item_y_long_name)

It is hard to see all the contents in the Jupyter Notebook Cell as the return will display in a single line.

The following code is trying to split the return items:

def test():
    return (1,2), (3,4)

print("test:", test())

def test2():
    return (
        1,2
    ), 
    (
        3,4
    )

print("test2:", test2())

Here is the output:

test: ((1, 2), (3, 4))
test2: ((1, 2),)

The test2 is not work as expected. How to write the correct return in the test2?

CodePudding user response：

Just add extra parenthesis to wrap the return properly then the return is spread across multiple lines.

def test():
    return (1,2), (3,4)

print("test:", test())

def test2():
    return ((
        1,2
    ), 
    (
        3,4
    ))

print("test2:", test2())

# output
test: ((1, 2), (3, 4))
test2: ((1, 2), (3, 4))
