Hi Peter.
Sadly (for me), you're right... then the only way to use doctest to
work both in 2.6 and 3.1 (without modifications between them) is
something like this:
#!/usr/bin/env python
'''
>>> str(concat('hello','world'))
'hello world'
'''
from __future__ import unicode_literals
def concat( first, second ):
return first + ' ' + second
if __name__ == "__main__":
import doctest
doctest.testmod()
Is there any way to avoid using str(...) to protect the string?
M.
---------------------------------------
#!/usr/bin/env python
'''
>>> concat('hello','world')
'hello world'
'''
from __future__ import unicode_literals
def concat( first, second ):
return first + ' ' + second
if __name__ == "__main__":
import doctest
doctest.testmod()
