In general, the only thing I've found annoying about Python are the scoping

>>> def fact(n):
..     def fact_iter(n,result):
..       if not n:  return result
..       else:      fact_iter(n-1,n*result)
..     return fact_iter(n,1)
>>> fact(3)
Traceback (innermost last):
  File "<stdin>", line 1, in ?
  File "<stdin>", line 5, in fact
  File "<stdin>", line 4, in fact_iter
NameError: fact_iter
>>> def curried_mult(x):
..     return lambda y: x*y
>>> curried_mult(3)
<function <lambda> at 80e2aa0>
>>> curried_mult(3)(4)
Traceback (innermost last):
  File "<stdin>", line 1, in ?
  File "<stdin>", line 2, in <lambda>
NameError: x

Similarly, the only thing I've found missing from Python is C's
ternary operator, it would be nice to be able to do something like 
the following:

def max(x,y): return ((x>y) ? x : y)

Good luck.
