Proper indentation for the second line of a multiline code with parentheses

Question

What is the recommended standard indentation for the second line of a multiline Python code with parentheses/commas?

1. No indentation:

   plt.imshow(np.transpose(Z), extent=[0,4.2,0,48000], cmap='jet',
   vmin=-100, vmax=0, origin='lowest', aspect='auto')
   

2. 4 spaces indentation:

   plt.imshow(np.transpose(Z), extent=[0,4.2,0,48000], cmap='jet',
       vmin=-100, vmax=0, origin='lowest', aspect='auto')
   

3. Identation up to the (:

   plt.imshow(np.transpose(Z), extent=[0,4.2,0,48000], cmap='jet',
              vmin=-100, vmax=0, origin='lowest', aspect='auto')
   

4. Another solution?

This is linked: Proper indentation for Python multiline strings but here the question is specific to multiline with parentheses / commas, and not strings.

Answer 1

If you follow PEP8, Indentation then I would go with option 3:

# Aligned with opening delimiter.
foo = long_function_name(var_one, var_two,
                         var_three, var_four)

I personally really like this option as it makes things clearer to read for myself and others. But if you are working at a company make sure to check with the company standards (each company might have their preference).

Answer 2

I would never use options 1 or 2, they can be misleading. 3 is good if you have enough room.

There is one more option which can be used when option 3 leaves too little room or when splitting lines using a backslash (PyCharm defaults to this in the latter situation), two indentation levels (8 spaces):

plt.imshow(np.transpose(Z), extent=[0,4.2,0,48000], cmap='jet',
        vmin=-100, vmax=0, origin='lowest', aspect='auto')

def grouper_with_prev(iterable: _Iin[_T], n: int, include_first: bool = False) \
        -> _Iout[_t.Tuple[_T, ...]]:
    """
    Returns n size chuncks of iterable with the previous n-1 elements

    """
    ...

This doesn't have the confusion of options 1 and 2, making it obvious what you're doing.
