Hi,
thanks to all who answered.
I'm using Python 2.6.5 on my machine and consulted the corresponding
documentation.
I do appreciate the modified definition of python 3, that seems much
more reasonable.
Thanks for indicating.
Greetings from Munich in Winter

being a causal python user (who likes the language quite a lot)
it took me a while to realize the following:

False
Section 5.9 Comparison describes this.
Can someone give me examples of use cases

The use cases for an order that works across types like int and str are weak
to non-existent. Implementing it was considered a mistake and has been fixed
in Python 3:
5> "5"
Traceback (most recent call last):
File "<stdin>", line 1, in<module>
TypeError: unorderable types: int()> str()
If you actually need to perform comparisons across types, you can rely
upon the fact that tuple comparisons are non-strict and use e.g.:
> a = 5
> b = '5'
> (type(a).__name__, a)< (type(b).__name__, b)
True
> (type(a).__name__, a)> (type(b).__name__, b)
False
The second elements will only be compared if the first elements are equal
(i.e. the values have the same type).
