Thinking of                           lambda args: expression
as more or less abbreviating  def <lambda>(args): return expression
should fill you in.

Two differences:
1. the first is an expression and can be used as such within other 
expressions;
    the second a statement that stands alone.
2. the first will compile (with proper substitutions for 'args' and 
'expression');
    the second will not, because '<lambda>' is not a legal name.

However, in CPython, '<lambda>' *is* the .func_name attribute of 
lambda-defined functions (so they are not quite anonymous;-).
