print a
print b

:-)

You just don't get the same species of resilient cockroach-like bugs
that you do in, say, C or C++.  No compilation stage, no memory
allocation bugs, no hideous C++ complexity, so personally I find print
statements quite sufficient.  This is particularly useful thanks to
the consistent (ish) use of __repr__ and __str__ everywhere.  Other
people swear by pdb and various IDEs, though.
