How can I remove a ppa using python apt module?

Question

I am able to add a ppa using it but cannot remove. I cannot find the correct syntax to remove the ppa from sources.list. Here's my code:

import aptsources.sourceslist as s
repo = ('deb', 'http://ppa.launchpad.net/danielrichter2007/grub-customizer/ubuntu', 'xenial', ['main'])
sources = s.SourcesList()
sources.add(repo)
sources.save()

#doesn't work 
sources.remove(repo)

I tried reading the docs found here but I still cannot find the format to call sources.remove(repo)

I dislike undocumented syntaxes ALOT..... have you tried exrepo = 'ppa.launchpad.net/danielrichter2007/grub-customizer/ubuntu' Basically try different components for the exrepo variable. — David

The SourcesList.remove() help text reads remove(source_entry), which indicates that what it wants is a SourceEntry object. As it hapens, sources.add() returns a SourceEntry object:

import aptsources.sourceslist as sl

sources = sl.SourcesList()
entry = sources.add('deb', 'mirror://mirrors.ubuntu.com/mirrors.txt', 'xenial', ['main'])
print(type(entry))

Outputs:

<class 'aptsources.sourceslist.SourceEntry'>

To remove the entry:

sources.remove(entry)
sources.save()

You can also disable it (which will leave a commented-out entry in sources.list:

entry.set_enabled(False)
sources.save()

I'm using this to do the removing for now.

import fileinput 

filename = '/etc/apt/sources.list'
word = 'grub-customizer'
n = ""
remove = fileinput.input(filename, inplace=1)
for line in remove:
    if word in line:
       line = n
    line.strip()
    print line,
remove.close()
