Loops

Loops allow for a section of code to be repeated - usually once for each value in a collection or range.

• for key in dictionary { code }

Executes the specified code for each key in the provided dictionary.

• for item in array { code }

Executes the specified code for each item in the provided array.

• for index in range(start, stop, [step]) { code }

Executes the specified code for each integer in the inclusive range between start and stop. If step is not specified, it's value is 1. range(1, 5) is equivalent to [1,2,3,4,5] and range(1, 5, 2) is equivalent to [1,3,5].
