{} are for JSON objects, which are called dict in Python
Here's how your JSON file should look:
{
"maps": [
{
"id": "blabla",
"iscategorical": "0"

What's the best way to set a single pixel in an HTML5 canvas?
...ba("+r+","+g+","+b+","+(a/255)+")";
ctx.fillRect( x, y, 1, 1 );
You can test the speed of these here: http://jsperf.com/setting-canvas-pixel/9 or here https://www.measurethat.net/Benchmarks/Show/1664/1
I recommend testing against browsers you care about for maximum speed. As of July 2017, fillR...
How do I compare strings in Java?

== tests for reference equality (whether they are the same object).
.equals() tests for value equality (whether they are logically "equal").

Using getopts to process long and short command line options
...get "--" as the flag. Then anything following that becomes OPTARG, and you test the OPTARG with a nested case.
This is clever, but it comes with caveats:
getopts can't enforce the opt spec. It can't return errors if the user supplies an invalid option. You have to do your own error-checking as y...

I did few tests and here is my understanding of what is happening here.
Short version
The ALTER TABLE statement that adds, drops or alters a column implicitly takes a schema modify (SCH-M) lock on the table, which has nothing to do w...
Check if a number is int or float
...>> if isinstance(x, int):
print 'x is a int!'
x is a int!
_EDIT:_
As pointed out, in case of long integers, the above won't work. So you need to do:
>>> x = 12L
>>> import numbers
>>> isinstance(x, numbers.Integral)
True
>>> isinstance(x, int)
