# Collections 

# 

# Provides common interface for dictionaries and lists. If a string is passed 

# in, it is split and then treated as a list. Optimized for convenience rather 

# than for large collections. Sorting versus the key is used to avoid randomness 

# in the ordering of the dictionary-based collections.
