More complete than pdb.py. Supports a “restart” command, disassembly, stack traces that give better information for exec statements, and stepping over “defs”. Tries to follow gdb’s commands unless there is good reason not to.

OpenC++ is C++ frontend library (lexer+parser+DOM/MOP) and source-to-source translator. OpenC++ enables development of C++ language tools, extensions, domain specific compiler optimizations and runtime metaobject protocols.

Python ternary operator
Today’s Python discovery:
Python doesn’t have the C style ?: ternary operator (e.g.: cond ? valueIfTrue : valueIfFalse).
But as of Python 2.5 it has a ternary operator with its own syntax: value_when_true if condition else value_when_false
For example:
>>> 'a' if 1 == 1 else 'b' 'a' >>> 'a' if 1 == 0 else 'b' 'b'
This is actually clearer and more Pythonic than that ?:
Unfortunately, for Python versions < 2.5, you don’t have this. I’ve seen people use: (condition and [value_when_true] or [value_when_false])[0]
IMHO, this is clever - in a bad way. Yuck. Personally, I think I’d rather just do:
def if_cond_val1_else_val2(cond, val1, val2): if cond: return val1 else: return val2
This adds 3 lines to your program (or 1 if you stick it in a module that you import from your programs) and won’t cause your colleagues to hate you.

Song from the Bank of America Commercial
A recent B of A commercial has a female acoustic singer/songwriter song, which sounds very similar to Shawn Colvin to me, but alas, it’s not Shawn Colvin.
It’s “Merry-Go-Round” by Antje Duvekot
