>Generators are not inherently faster as they were made to allow for lazy computation, which saves memory rather than time. However, the saved memory can be cause for your program to actually run faster. How? Well, if you have large dataset and you don't use generators (iterators), then the data might overflow CPUs L1 cache, which will slow down lookup of values in memory significantly. Can someone chime in about the L1 cache? The claim is made without measurements, so I am skeptical.
