Python tutorial says "Use spaces around operators and after commas, but not directly inside bracketing constructs: a = f(1, 2) + g(3, 4)." What does "not directly inside bracketing constructs" exactly mean?

That probably comes from PEP 8 -- Style Guide for Python Code. Specifically, see the section on "Whitespace in Expressions and Statements."
From that section:
Avoid extraneous whitespace in the following situations:
- Immediately inside parentheses, brackets or braces.
Yes: spam(ham[1], {eggs: 2})
No: spam( ham[ 1 ], { eggs: 2 } )

It means you shouldn't do things like a = f ( 1 ) or l = [ 2, 3 ].

I think it means do this:
x = (1, 2)
not this:
x = ( 1, 2 )
