It is possible derive your own string class from the built-in one and
override what 'repr' does (and make it do whatever you want). Here's an
example of what I mean:
##### Sample #####
# -*- coding: iso-8859-1 -*-
# Special string class to override the default
# representation method. Main purpose is to
# prefer using double quotes and avoid hex
# representation on chars with an ord > 128
class MsgStr(str):
def __repr__(self):
asciispace = ord(' ')
if self.count("'") >= self.count('"'):
quotechar = '"'
else:
quotechar = "'"
rep = [quotechar]
for ch in self:
if ord(ch) < asciispace:
rep += repr(str(ch)).strip("'")
elif ch == quotechar:
rep += "\\"
rep += ch
else:
rep += ch
rep += quotechar
return "".join(rep)
if __name__ == "__main__":
s = MsgStr("\tWürttemberg\"")
print s
print repr(s)
print str(s)
print repr(str(s))
