Can I use string formatting in my own functions, or is it stuck with builtins?
It doesn't make much sense for me, but I don't understand the following
error:
In [1]: var = 456
In [2]: def printd(arg):
...: print('>>> %s') % arg
...:
In [3]: printd(var)
>>> 456
In [4]: printd('Variable is %s') % var
>>> Variable is %s
---------------------------------------------------------------------------
exceptions.TypeError Traceback (most recent
call last)
/home/tiago/<console>
TypeError: unsupported operand type(s) for %: 'NoneType' and 'int'
Thanks,
Tiago.
