Marco Giordano shows why using dictionaries are so useful when using Python in Autodesk Maya, showing how to extract large amounts of data from a scene and save the data into a text file to be later read back into Maya.
In the tutorial I will show you how can you extract a lot of data from the scene and then save it to a text file and read it back
Marco describes Dictionaries as something almost similar to an array. The major difference being that with dictionaries you are able to store values by keys, while the array stores values by index. Storing values by keys allows you to quickly find the stored data by simply asking the Dictionary.
