Hello,
I would like to count list items but am not 100% sure how to do it.
Here is what I have so far:
for brain in brains:
x = getattr(brain, horizontal)
y = getattr(brain, vertical)
if x and y and (x, y) in table:
table[(x, y)] += 1
table[(x, '')] += 1
table[('', y)] += 1
table[('', '')] += 1
but when I run this, I get the following error on the line:
if x and y and (x, y) in table:
TypeError: list objects are unhashable
where:
x = ['airlines-scheduled', 'airport-car-parking']
I am basically looping through files within each file, I have an entity,
for example:
file1
<topic>airlines-scheduled airport-car-parking</topic>
file2
<topic>airport-car-parking</topic>
etc...
So the above code counts all occurrences of 'airport-car-parking' and
sums it up.
All works well if, I change the code to:
for brain in brains:
x = getattr(brain, horizontal)
x = string.join(x, '' )
y = getattr(brain, vertical)
y = string.join(y, '' )
if x and y and (x, y) in table:
table[(x, y)] += 1
table[(x, '')] += 1
table[('', y)] += 1
table[('', '')] += 1
So now my list becomes a string, which is not really good for me, as
this fails when there is more then one item.
Is there a better way to loop through this and sum up all occurrences of
each entry ie 'airport-car-parking'
Cheers
Norman
