python - Find the last substring after a character -

-

I know how to find a substring: from start index to letters between the end, etc., but I have problems Which I do not know how to solve: I have a string, for example a path: folder1 / folder2 / folder3 / new_folder / image.jpg and another path: folder1 / folder2 /folder3/folder4/image2.png

And from this path I only want to take the previous parts: image.jpg and image2.png . If I do not know when it starts (I do not know the index, but I think it will be after the last / character) How can I get a substrings, if at times Letter repeats ( / ) and extensions are different ( .jpg and .png even more)?

os.path.basename ()

Returns the file name of your path: < / P> 

  & gt; & Gt; & Gt; Import os.path & gt; & Gt; & Gt; Os.path.basename ('Folder 1 / folder2 / folder3 / new_folder / image.jpg') 'image.jpg'
For a more common string splitting problem, you use to split

The string on the given alphabet sequence count from the end : 

  & gt; & Gt; & Gt; 'Foo: bar: baz'.rpartition (': ') (' foo: bar ',': ',' baz ')> gt; & Gt; & Gt; 'Foo: bar: baz'.rpartition (': ') [- 1]' falcon '

and with you several times to a limit, you can redistribute from the end : 

  & gt; & Gt; & Gt; 'Foo: Bar: Baaz: Spam: Eggs'. Finally, but at least, you search from the end (':', 3) ['Foo: Bar', 'Buzz', 'Spam', 'Egg']

Taxes can find just a substring indicator: 

  & gt; & Gt; & Gt; 'Foo: Bar: baz'.rfind (': ') 7

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project.
