py_string

A library that provides methods equivalent to Python 3's str class in C ++
A class that reproduced the Python str class

Installation

Since this is a single header library, it is easy to use by include only.

How to use

Since it inherits std::string, it can be handled like std::string. Think that you can use python's str type method with std::string.

#include "py_string.hpp"

multiplication

py::string str = "hello world!";

std::cout << str * 2 << std::endl;
//hello world!hello world!

formatting for title style

std::cout << str.title() << std::endl;
//Hello World!

splitting

py::string str2 = "12,3,4-2,2,3";
std::deque<py::string> slist; //std::vector is also acceptable

str2.split(slist, ",");

for (auto &&s : slist)
{
    std::cout << s << std::endl;
}
//12
//3
//4-2
//2
//3

formatting

py::string str3 = "{0} format string{1}";
std::cout << str3.format("let's", "!") << std::endl;
//let's format string!
py::string str4 = "{}{}{}";
std::cout << str4.format("1", 2, "3") << std::endl;
//123

py::string str = "{0},{1},{0}";
std::cout << str.format("apple", "banana") << std::endl;
//apple,banana,apple

string slicing

py::string str5 = "0123456789";
std::cout << str5[{0,5}] << std::endl;
//01234
std::cout << str5[{py::nullopt, py::nullopt, -1}] << std::end;
//9876543210

reverse order access

std::cout << str5[-1] << std::endl;
//9
std::cout << str5[-3] << std::endl;
//7

For more detailed usage of this library, please refer to example.cpp.

The behavior of each method is almost the same as that of python's str type. Please see python's official support for details.
