ASCII encryption program in Python
Just a few notes about print, I see you're not using parenthesis so i'm guessing you're using python 2.x.  I would urge you to switch to python 3.5+ now, as python 2.x is at end of life.  However if you insist on using it

-Keep consistent on using parenthesis

-You can use \n inside the string to add a newline:

print "Hello World!\n"


If you switch to python 3.x you can use the print function and pass in the end parameter to append a new line after your string:

s = "Hello World!"
print(s, end='\n') #NOTE: @Coal_ points out this is the default
# so if you didn't want there to be a newline you'd have to overwrite
# print(s, end=' ')
# @Solomon, and if you wanted a space between your outputs,
# print(s, end='\n\n')


That way you don't have seemingly useless print statements everywhere.
