Lists are one of the fundamental data collections in python (we will also discuss dictionaries and you may want to read about tuples and sets).
Data Collections: Dictionaries
Dictionaries are another basic python data collection. Dictionaries store data in pairs, with a set of unique keys each mapped to some value (the values do not have to be unique). Dictionaries are extremely useful in scripting. For example, imagine that we are reducing a complex set of observations and want to be able to look up a the calibrator associated with a given source.
