int("7") -> 7
int(" 7") -> 7
int("aa7aa") ->ValueError: invalid literal for int(): aa7aa. You'd 
need to remove the non-digits using replace or re.sub.

Are you asking what numeric value passed to chr() gives Enter (etc)? 
If so consult any ASCII Chart. One is at
http://www.lookuptables.com/. Of course Enter in ASCII is CR.
