Hi everybody,
I was wondering if anyone can explain this. My understanding is that 'is'
checks if the object is the same. However, in that case, why this
inconsistency for short strings? I would expect a 'False' for all three
comparisons. This is reproducible across two different machines, so it is
not just a local quirk. I'm running Debian etch with Python 2.4.4 (the
default).
Thanks, Faheem.
In [1]: a = '--'
In [2]: a is '--'
Out[2]: False
In [4]: a = '-'
In [5]: a is '-'
Out[5]: True
In [6]: a = 'foo'
In [7]: a is 'foo'
Out[7]: True
