Detailed Description

Python-like utilities and data structures for C++.

The py namespace contains implementations of Python-inspired data structures and utilities that make C++ programming more convenient and Python-like.

Function Documentation

◆ const_enumerate()

template<typename T >

auto py::const_enumerate ( const T & iterable ) -> detail::EnumerateIterableWrapper<const T>

inline

(deprecated) Create an enumerable wrapper for a const container

Deprecated:: Use enumerate() instead. This function is provided for backward compatibility.

Template Parameters

T	The container type

Parameters

[in] iterable Const reference to the container to enumerate

Returns: detail::EnumerateIterableWrapper<const T> Wrapper for enumerated iteration

◆ enumerate() [1/2]

template<typename T >

auto py::enumerate ( const T & iterable ) -> detail::EnumerateIterableWrapper<const T>

inline

Create an enumerable wrapper for a const container.

Returns a wrapper that allows iteration over container elements with their indices, similar to Python's enumerate() function. Used for const containers.

Template Parameters

T	The container type

Parameters

[in] iterable Const reference to the container to enumerate

Returns: detail::EnumerateIterableWrapper<const T> Wrapper for enumerated iteration

◆ enumerate() [2/2]

template<typename T >

auto py::enumerate ( T & iterable ) -> detail::EnumerateIterableWrapper<T>

inline

Create an enumerable wrapper for a container.

Returns a wrapper that allows iteration over container elements with their indices, similar to Python's enumerate() function.

Template Parameters

T	The container type

Parameters

[in] iterable Reference to the container to enumerate

Returns: detail::EnumerateIterableWrapper<T> Wrapper for enumerated iteration

◆ len() [1/2]

template<typename Key , typename T >

auto py::len ( const dict< Key, T > & m ) -> size_t

inlinenoexcept

Get the number of key-value pairs in a dictionary.

Template Parameters

Key	The key type
T	The value type

Parameters

[in] m The dictionary

Returns: size_t Number of key-value pairs

◆ len() [2/2]

template<typename Key >

auto py::len ( const set< Key > & m ) -> size_t

inlinenoexcept

Get the number of elements in a set.

Template Parameters

Key	The element type stored in the set

Parameters

[in] m The set

Returns: size_t Number of elements in the set

◆ operator<() [1/2]

template<typename Key , typename T >

auto py::operator<	(	const Key &	key,
		const dict< Key, T > &	m
	)		-> bool

inlinenoexcept

Check if a key is contained in a dictionary.

Template Parameters

Key	The key type
T	The value type

Parameters

[in]	key	The key to check
[in]	m	The dictionary to search

Returns: true if the key is contained in the dictionary, false otherwise

◆ operator<() [2/2]

template<typename Key >

auto py::operator<	(	const Key &	key,
		const set< Key > &	m
	)		-> bool

inline

Check if an element is contained in a set.

Template Parameters

Key	The element type stored in the set

Parameters

[in]	key	The element to check
[in]	m	The set to search

Returns: true if the set contains the element, false otherwise

◆ range() [1/2]

template<typename T >

CONSTEXPR14 auto py::range	(	T	start,
		T	stop
	)		-> Range<T>

range(T start, T stop)

The range(T start, T stop) function is creating a range of values from start to stop. It returns a Range<T> object that represents the range. The range includes all values from start up to, but not including, stop.

Template Parameters

T	The numeric type for the range values

Parameters

[in]	start	The starting value of the range (inclusive)
[in]	stop	The ending value of the range (exclusive)

Returns: Range<T>

◆ range() [2/2]

template<typename T >

CONSTEXPR14 auto py::range ( T stop ) -> Range<T>

range(T stop)

The range(T stop) function is creating a range of values from 0 to stop. It returns a Range<T> object that represents the range. The range includes all values from 0 up to, but not including, stop.

Template Parameters

T	The numeric type for the range values

Parameters

[in] stop The ending value of the range (exclusive)

Returns: Range<T>

◆ swap()

template<typename T >

void py::swap	(	RecursiveGenerator< T > &	a,
		RecursiveGenerator< T > &	b
	)

noexcept
