Allow 2 spaces after an import block

[dwaynebailey]

While PEP8 is unclear about how many lines after the import block it does say this:
"Separate top-level function and class definitions with two blank lines."

So in our code we add two lines after imports to closely match our high level double line breaks.

This probably isn't what other people do so being able to set the blank line following an import block would be a good option

Hi @dwaynebailey,

Thanks for pointing out this area for improvement. Currently, isort does add 2 lines if it sees the next item code construct is a class, decorator, or function - but one line otherwise. To fix the issue you are facing I plan on adding a "lines_after_import" option, that when set to a number of new lines will force this number independent to the code construct that follows.

Thanks!

Thanks for reporting this issue, it has been fixed in version 3.5.0 with the addition of the 'lines_after_imports' setting.

Thanks for all these changes. Tested and seems to be working great.

@timothycrosley lines_after_import=2 does not help in all cases unfortunately:

if sys.version > (3, 8):
  import xxx

  class Abc:
    ...

In this example, I would like to have lai=1 for non-top-level imports. 🤷‍♂️🤷‍♂️🤷‍♂️
