Python PEP8: Blank lines convention

I am interested in knowing what is the Python convention for newlines between the program parts? For example, consider this:

import os

def func1():

def func2():

What should be the ideal newline separation between:

1. The import m开发者_如何学Codules and the functions?
2. The functions themselves?

I have read PEP8, but I wanted to confirm the above two points.

1. Two blank lines between the import statements and other code.
2. Two blank lines between each function.

If one will check with 'Blank Lines' section of PEP8 — one will find the following:

Surround top-level function and class definitions with two blank lines.

Method definitions inside a class are surrounded by a single blank line.

Extra blank lines may be used (sparingly) to separate groups of related functions. Blank lines may be omitted between a bunch of related one-liners (e.g. a set of dummy implementations).

Use blank lines in functions, sparingly, to indicate logical sections.

Regarding imports, PEP8 states:

Imports should usually be on separate lines

...

Imports should be grouped in the following order:

1. standard library imports
2. related third party imports
3. local application/library specific imports

You should put a blank line between each group of imports.

So, for your example, PEP8 compliant formatting would be:

import os


def func1():


def func2():

Just to give a more comprehensive illustration:

import re
import glob
import sys

import requests
import scrapy

from flask import Flask
from my_local_module import MyClass


def top_level_function1():
    pass


def top_level_function2():
    pass


class TestClass(object):
    
    def class_method1():
        pass

    def class_method2():
        pass


class TestClass2(object):
    
    def class2_method1():
        pass

    def class2_method2():
        pass

Just a simple modification

#Standard system imports
import re
import glob
import sys

#Related third party imports
import requests
import scrapy
from flask import Flask

#Local application/library specific imports
from my_local_module import MyClass1, MyClass
