I'm trying to achieve a simple solution to requiring to pack a value alongside an integer, so it can be easily remembered at a later time.
class keep_index:
def __init__(self, value, index):
self.value = str(value)
self.index = index
def __call__(self):
return self.index
def __str__(self):
return self.value
x = keep_index(4, 1)
print x
print x()
As you can see, this works. Printing x, prints out 4. But calling it returns a value I added alongside it. However, it is a string in my example, not an integer. I have tried __int__ instead of __str__ of course. That was my first attempt, but that doesn't work.
Since I got this far by trial and error by dir()'ing some of the classes like "int" and "str", I may be missing something blatantly obvious. Sorry to be a pain.
Another problem, is if I put 'x' inside a list, and print the list, it displays the function address rather then the value of ".value". And I'd rather not change the concept behind how this is working. I believe that packing an "
invisible" value alongside the original would work beautifully.
