From Wikipedia,
A letter is a segmental symbol of a phonemic writing system. The inventory of all letters forms the alphabet. Letters broadly correspond to phonemes in the spoken form of the language, although there is rarely a consistent, exact correspondence between letters and phonemes

Sample Output:

Orginal string: Py@th12on
Remove all characters from the said string which are non-letters: Python

Orginal string: Python 3.0
Remove all characters from the said string which are non-letters: Python

Orginal string: 2^sdfds*^*^jlljdslfnoswje34u230sdfds984
Remove all characters from the said string which are non-letters: sdfdsjlljdslfnoswjeusdfds
