itertools

Classes

iterator_facade
iterator_facade<Iter,Value,std::forward_iterator_tag,Reference,Difference>	CRTP base class for various iterator types in itertools.
sentinel_t	Generic sentinel type that can be used to mark the end of a range.
enum_iter	Iterator for an itertools::enumerated range.
enumerated	Represents an enumerated range.
prod_iter	Iterator for a itertools::multiplied (cartesian product) range.
multiplied	Represents a cartesian product of ranges.
range	A lazy range of integers that mimics a Python range.
sliced	Represents a sliced range.
stride_iter	Iterator for a itertools::strided range.
strided	Represents a strided range.
transform_iter	Iterator for a itertools::transformed range.
transformed	Represents a transformed range.
zip_iter	Iterator for a itertools::zipped range.
zipped	Represents a zipped range.

Functions

make_sentinel	Create an itertools::sentinel_t from an iterator using template type deduction.
enumerate	Lazy-enumerate a given range (similar to Python’s enumerate).
product	Lazy-multiply a given number of ranges by forming their cartesian product.
make_product	Create a cartesian product range from an array of ranges.
product_range	Create a cartesian product range of integer ranges from given integers.
foreach	Apply a function to every element of an integer itertools::range.
distance	Calculate the distance between two iterators.
make_vector_from_range	Create a vector from a range.
chunk_range	Given an integer range [first, last), divide it as equally as possible into N chunks.
slice	Lazy-slice a given range.
stride	Lazy-stride through a given range.
transform	Lazy-transform a given range by applying a unary callable object to every element of the original range.
zip	Lazy-zip ranges together (similar to Python’s zip).
