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 following is an example 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> >>> list(zip( xi, yi )) [(1.47, 52.21), (1.5, 53.12), (1.52, 54.48), (1.55, 55.84), (1.57, 57.2), (1.6, 58.57), (1.63, 59.93), (1.65, 61.29), (1.68, 63.11), (1.7, 64.47), (1.73, 66.28), (1.75, 68.1), (1.78, 69.92), (1.8...
