In a given word you need to check if one symbol goes only right after another.
Cases you should expect while solving this challenge:
- one of the symbols is not in the given word - your function should return False;
- any symbol appears in a word more than once - use only the first one;
- two symbols are the same - your function should return False;
- the condition is case sensitive, which means 'a' and 'A' are two different symbols.
Input: Three arguments. The first one is a given string (str), second is a symbol (str) that should go first, and the third is a symbol (str) that should go after the first one.
Output: A logic value (bool).
assert goes_after("world", "w", "o") == True assert goes_after("world", "w", "r") == False assert goes_after("world", "l", "o") == False assert goes_after("panorama", "a", "n") == True

Sync solutions into your local folder
(in beta testing) Launch local server so your browser can use it and sync solution between local file end extension on the fly. (doesn't work for safari)
checkio serv -d
Alternatevly, you can install Chrome extension or FF addon
