Hi, guys. Here is a demo program like this:
aa = 3

print cc
I put a breakpoint at the first line, then debug the program.
After 'aa' is set to '3', I modify '53' in the 3rd line to '34',

save the source file and run remain codes. As expected,

What is the adventage of this form to simply writing d = {'one': 1, 'two': 2}?
Is there any difference?

The first approach does not really give you any variable (in easy form) to
operate upon.
The second approach returns a dict object that you can later reuse in easier
form. So one advantage is certainly that ease of object reuse and also
object modification.

Sorry, I am afraid, I was not clear enough. So what is the difference

I think the way - d = dict({'one': 1, 'two': 2}) can be used to created
dictionary using list comprehension.
e.g.
d = dict((i,i**2) for i in range(10))
d
{0: 0, 1: 1, 2: 4, 3: 9, 4: 16, 5: 25, 6: 36, 7: 49, 8: 64, 9: 81}
I do not think the second approach can be used in this fashion.

Never put a lone dict literal {...} inside a call to dict(), that's just a
waste of time. Just use the literal on its own.
That's what I thought about this, I just didn't want to believe that
