Say x can be a string or None.
>>> for x in ["a string", None]:
... "{:20}".format(x)
...
'a string '
Traceback (most recent call last):
File "<stdin>", line 2, in <module>
TypeError: unsupported format string passed to NoneType.__format__
The string can be padded while None does not support that. The best solution
is usually to replace None with a string that cannot occur normally, and
then to use that instead of None. Example:
>>> for x in ["a string", None]:
... "{:20}".format("#NONE" if x is None else x)
...
'a string '
'#NONE '
Slightly more convenient: you can force string conversion before padding:
>>> for x in ["a string", None]:
... "{!s:20}".format(x)
...
'a string '
'None '
