The zip() function interleaves values from several iterators or sequences. It will create n tuples from the values in each of the n input iterables or sequences. We used it in the previous section to interleave data points from two sets of samples, creating two-tuples.

The zip() function is a generator. It does not materialize a resulting collection.

The following is an example of code that shows what the zip() function does:

>>> xi= [1.47, 1.50, 1.52, 1.55, 1.57, 1.60, 1.63, 1.65,... 1.68, 1.70, 1.73, 1.75, 1.78, 1.80, 1.83,] 
>>> yi= [52.21, 53.12, 54.48, 55.84, 57.20, 58.57, 59.93, 61.29,... 63.11, 64.47, 66.28, 68.10, 69.92, 72.19, 74.46,] >>> zip( xi, yi ) <zip object at 0x101d62ab8> >>> ...
