The try block contains an expression that will always evaluate
to True or False and thus never rai

works well and prints the result which comes from db to the text widget.
When user searches in entrybox the list lowers down to 1 item, how can i
get the index of that item and bind it to the button so it will print the

try... except is meant to catch errors: places where your program would
otherwise crash. It does NOT work as a truth check.
In your example:

Let's try this interactively:
>>> uvc = 2
>>> type(uvc)
>>> type(uvc) == float
False
So calling type(uvc) doesn't raise an error. It returns the type
"int". You then c

I'm trying to get a list of tuples to be a float, a numerator, and a
denominator for all the fractions: halves, thirds, fourths etc up to
ninths. 1/2 returns the same float as 2/4, 3/6, 4/8. I would like to keep
only the 1/2. When I try (line 18) to "pop" from the list I get a "TypeError:
