+[![Build Status](https://travis-ci.org/kimwalisch/primesieve-python.svg?branch=master)](https://travis-ci.org/kimwalisch/primesieve-python) [![PyPI](https://img.shields.io/pypi/v/primesieve.svg)](https://pypi.python.org/pypi/primesieve)
+
+# Summary
+
+Python bindings for the [primesieve](https://github.com/kimwalisch/primesieve)
+C++ library.
+
+Generates primes orders of magnitude faster than any pure Python code!
+
+**Features:**
+
+* Get an array of primes
+* Iterate over primes using little memory
+* Find the nth prime
+* Count/print primes and [prime k-tuplets](https://en.wikipedia.org/wiki/Prime_k-tuple)
+* Multi-threaded for counting primes and finding the nth prime
+* NumPy support
+
+# Prerequisites
+
+We provide primesieve wheels (distribution packages) for Windows, macOS
+and Linux for x86 and x64 CPUs. For other operating systems and/or CPUs
+you need to have installed a C++ compiler.
+
+```bash
+# Ubuntu/Debian
+sudo apt install g++ python-dev
+
+# Fedora
+sudo dnf install gcc-c++ python-devel
+
+# macOS
+xcode-select --install
+```
+
+# Installation
+
+```bash
+# Python 3.5 or later
+pip install primesieve
+
+# For Python 2.7 use:
+pip install "primesieve<=1.4.4"
+```
+
+# Conda Installation
+
+[![TravisCI](https://travis-ci.org/conda-forge/python-primesieve-feedstock.svg?branch=master)](https://travis-ci.org/conda-forge/python-primesieve-feedstock)
+[![AppVeyor](https://ci.appveyor.com/api/projects/status/github/conda-forge/python-primesieve-feedstock?svg=True)](https://ci.appveyor.com/project/conda-forge/python-primesieve-feedstock/branch/master)
+[![Circle CI](https://circleci.com/gh/conda-forge/python-primesieve-feedstock.svg?style=shield)](https://circleci.com/gh/conda-forge/python-primesieve-feedstock)
+[![Anaconda-Server Badge](https://anaconda.org/conda-forge/python-primesieve/badges/downloads.svg)](https://anaconda.org/conda-forge/python-primesieve)
+
+You don't need to install a C++ compiler when installing python-primesieve using Conda.
+
+```
+conda install -c conda-forge python-primesieve
+```
+
+# Usage examples
+
+```Python
+>>> from primesieve import *
+
+# Get an array of the primes <= 40
+>>>  primes(40)
+[2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37]
+
+# Get an array of the primes between 100 and 120
+>>>  primes(100, 120)
+[101, 103, 107, 109, 113]
+
+# Get an array of the first 10 primes
+>>>  n_primes(10)
+[2, 3, 5, 7, 11, 13, 17, 19, 23, 29]
+
+# Get an array of the first 10 primes >= 1000
+>>>  n_primes(10, 1000)
+[1009, 1013, 1019, 1021, 1031, 1033, 1039, 1049, 1051, 1061]
+
+# Get the 10th prime
+>>> nth_prime(10)
+29
+
+# Count the primes below 10**9
+>>> count_primes(10**9)
+50847534
+```
+
+Here is a [list of all available functions](primesieve/_primesieve.pyx).
+
+# Iterating over primes
+
+Instead of generating a large array of primes and then do something
+with the primes it is also possible to simply iterate over the primes
+which uses less memory.
+
+```Python
+""">>> import primesieve
+
+it = primesieve.Iterator()
+prime = it.next_prime()
+
+# Iterate over the primes below 10000
+while prime < 10000:
+    print prime
+    prime = it.next_prime()
+
+# Set iterator start number to 100
+it.skipto(100)
+prime = it.prev_prime()
+
+# Iterate backwards over the primes below 100
+while prime > 0:
+    print prime
+    prime = it.prev_prime()"""
+
+from primesieve import primes_range
+
+# iterate over the primes in range between 100 and 10^7
+# 100 < prime <= 10^7
+for prime in primes_range(100,10e7):
+
+    # do something with the prime
+    ...
+
+```
+
+# NumPy support
+
+Using the ```primesieve.numpy``` module you can generate an array of
+primes using native C++ performance!
+
+In comparison the ```primesieve``` module generates an array of primes
+about 3 times slower mostly because the conversion of the C primes
+array into a python array is quite slow.
+
+```Python
+>>> from primesieve.numpy import *
+
+# Generate a numpy array with the primes below 100
+>>>  primes(100)
+array([ 2,  3,  5,  7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59,
+       61, 67, 71, 73, 79, 83, 89, 97])
+
+# Generate a numpy array with the first 100 primes
+>>>  n_primes(100)
+array([  2,   3,   5,   7,  11,  13,  17,  19,  23,  29,  31,  37,  41,
+        43,  47,  53,  59,  61,  67,  71,  73,  79,  83,  89,  97, 101,
+       103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167,
+       173, 179, 181, 191, 193, 197, 199, 211, 223, 227, 229, 233, 239,
+       241, 251, 257, 263, 269, 271, 277, 281, 283, 293, 307, 311, 313,
+       317, 331, 337, 347, 349, 353, 359, 367, 373, 379, 383, 389, 397,
+       401, 409, 419, 421, 431, 433, 439, 443, 449, 457, 461, 463, 467,
+       479, 487, 491, 499, 503, 509, 521, 523, 541])
+```
+
+# Development
+
+You need to have installed a C++ compiler, see [Prerequisites](#prerequisites).
+
+```bash
+# Install prerequisites
+pip install cython pytest numpy
+
+# Clone repository
+git clone --recursive https://github.com/kimwalisch/primesieve-python
+
+cd primesieve-python
+
+# Build and install primesieve-python
+pip install . --upgrade
+
+# Run tests
+pytest
+```
+
+# How to do a new release
+
+* You need to be a maintainer of the [primesieve-python](https://github.com/kimwalisch/primesieve-python) repo.
+* You need to be a maintainer of the [primesieve pypi](https://pypi.org/project/primesieve) project.
+* Compare ```.travis.yml``` with [cibuildwheel#example-setup](https://github.com/joerick/cibuildwheel#example-setup) and update ```.travis.yml``` if needed.
+* Update the supported Python versions in ```setup.py``` (we support the same versions as [cibuildwheel](https://pypi.org/project/cibuildwheel)).
+* Increment the primesieve-python version in ```setup.py```. Ideally this should be the last commit before the release as this uploads the new primesieve wheels to [https://test.pypi.org](https://test.pypi.org/project/primesieve/#files).
+* Check if all primesieve wheels (Windows, macOS, Linux) have been uploaded to [https://test.pypi.org](https://test.pypi.org/project/primesieve/#files).
+* If not, read the [Travis CI logs](https://travis-ci.org/github/kimwalisch/primesieve-python) and fix the bugs.
+* Finally, do a new release on GitHub.
