The square brackets alone make it a winner. Array, list and strings indexing. Dictionary lookups. Slices and substrings. List comprehensions. The notations convenience of this alone is immense.

Built in list, string, and dicts. For the 90% of code that is not performance critical, this is a godsend. Just looking at the c++ syntax for this makes me never want to use a stl data structure for anything trivial.
