Please see the documentation for examples and an API reference.
On any platform, use pip or conda.

conda install -c conda-forge slicerator
from slicerator import Slicerator @Slicerator.from_class class MyLazyLoader: def __getitem__(self, i): # this method will be wrapped by Slicerator, so that it accepts slices, # lists of integers, or boolean masks. Code below will only be executed # when an integer is used. # load thing number i return thing def __len__(self): # do stuff return number_of_things # Demo: >>> a = MyLazyLoader() >>> s1 = a[::2] # no data is loaded yet >>> s2 = s1[1:] # no data is loaded yet >>> some_data = s2
