New submission from Ian Remmel <des...@ianwremmel.com>:

This started as a bug report for httpie 
https://github.com/jakubroztocil/httpie/issues/717#issuecomment-426125261

And became a bug report for requests 
https://github.com/requests/requests/issues/4813

> But turned out to be an issue with Python's netrc parser:
> 
>
> it appears that auth via netrc is broken if ~/.netrc includes entries that 
> are not exactly login/password tuples. For example, I have the following 
> entries for circle ci and heroku:

>      login <redacted>
>      password <redacted>
>      method interactive
>    machine circleci.com
>      login <redacted>
> ```

> both of these entries prevent my entry for github.com from working with 
> httpie (but curl works just fine).


I've used the following script to test python 2.7 and 3.7:

```
import netrc
import os.path

netrc.netrc(os.path.expanduser('~/.netrc')).authenticators('api.github.com')
```

Python 2:
```
Traceback (most recent call last):
  File "test.py", line 4, in <module>
    netrc.netrc(os.path.expanduser('~/.netrc')).authenticators('api.github.com')
  File 
"/usr/local/Cellar/python@2/2.7.15_1/Frameworks/Python.framework/Versions/2.7/lib/python2.7/netrc.py",
 line 35, in __init__
    self._parse(file, fp, default_netrc)
  File 
"/usr/local/Cellar/python@2/2.7.15_1/Frameworks/Python.framework/Versions/2.7/lib/python2.7/netrc.py",
 line 117, in _parse
    file, lexer.lineno)
netrc.NetrcParseError: bad follower token 'method' (/Users/ian/.netrc, line 7)
````

Python 3:
```
Traceback (most recent call last):
  File "test.py", line 4, in <module>
    netrc.netrc(os.path.expanduser('~/.netrc')).authenticators('api.github.com')
  File

  File

 line 111, in _parse
    file, lexer.lineno)
netrc.NetrcParseError: bad follower token 'method' (/Users/ian/.netrc, line 7)
```
