Pythonic tool-belt for Swift – a Swift implementation of selected parts of Python standard library.

Pythonic.swift

Pythonic.swift is a Swift library implementating selected parts of Python's standard library and making them available to your Swift code.

import Pythonic allows you to write Python flavored code such as:

#!/usr/bin/env swift -I .

import Pythonic

if re.search("^foo", "foobar") {
    print("ok!")
}

if any(["foo", "bar", "zonk"]) {
    print(chr(ord("a"))) // a
}

var strings = ["foo", "bar"]
print(":".join(strings)) // foo:bar
if strings {
    print(strings[0]) // foo
}
if len(strings) == 2 {
    print(strings[1].upper()) // BAR
    print(strings[1].split("a")) // ["b", "r"]
}

var greeting = "   hello pythonista   "
if greeting.strip().startswith("hello") {
    print(greeting.strip().title()) // Hello Pythonista
}

var numbers = [1, 2, 3, 4, 5]
print(sum(numbers)) // 15
print(max(numbers)) // 5

Contributing

Code contributions are more than welcome! This is the quick guide to contributing:

1. Fork the project
2. Implement function foo from the Python standard library
3. Add a test case for foo in Pythonic-test.swift
4. Make sure the test case passes in both Python and Swift by running make test
5. Submit a pull request
6. Repeat until we're done :-)
