First digit after letter

Write a function @digit_after_let(s)@ that given a string $s$ returns a boolean and a character. The boolean is True when $s$ has some digit after some letter, otherwise is False. The character has to be the first digit in $s$ that comes out after some letter in the first case and the symbol ’$’ in the second one. You can use the string method @isalpha()@ to check whether given a string it has at least one character and all its characters are letters. For instance, @my_string.isalpha()@ is True when @my_string@ is ’HeLLo’ or ’X’ and is False when @my_string@ is ’He7TO’ or ’?;x’ or ’123456’.
