Case 1

The cursor is at | position (about to add second argument to print), and I press Enter:

Actual

def case1():
    print('first_argument', |)

It becomes:

def case1():
    print('first_argument', 
    |)

Expected 1

def case1():
    print('first_argument'
        |)

OR Expected 2 (this one is preferred)

def case1():
    print('first_argument'
          |)

Case 2

Actual

The cursor is right after the closing parenthesis and I press Enter.

def case2():
    print(
        'some_very_very_very_very_long_function_argument_',
        'second_argument')|

It becomes:

def case2():
    print(
        'some_very_very_very_very_long_function_argument_',
        'second_argument')
        |

Expected

def case2():
    print(
        'some_very_very_very_very_long_function_argument_',
        'second_argument')
    |

Case 3

Actual

The cursor after the comment. Press Enter:

def case3(): # some comment|

It becomes:

def case3(): # some comment
|

Expected

def case3(): # some comment
    |

Same with comments after for loops:

def case3(): # some comment
    for i in range(1): # another comment|

after pressing Enter becomes

def case3(): # some comment
    for i in range(1): # another comment
    |

Expected:

def case3(): # some comment
    for i in range(1): # another comment
        |

Also look at #3284

I agree with case 1. It makes sense to have the default indentation behavior comply with PEP8 (https://www.python.org/dev/peps/pep-0008/#indentation).

I’ve published a package that provides better python indentation. It’s still pretty immature, but has been working well for my purposes. https://marketplace.visualstudio.com/items?itemName=KevinRose.vsc-python-indent
