punycode 0.2.1

Punycode Converter Library for Python

You can convert Punycode domain to/from Unicode domain with only one function: punycode.convert().

How to use

Install

pip install punycode

Function

There is only one function punycode.convert().

• input:

input_text: string

Input can be both a Punycode domain and a Unicode domain.

• return:

output_text: string

If you input Punycode domain, the return will be a Unicode domian.

On the other hand, if you input a Unicode domain, you will get a Punycode domain.

Code sample

import punycode



# Convert Unicode domain to Punycode domain

str1 = "美しい.世界"

str2 = "こっち.みんな"

str3 = "日本語.jp"

print(f"{str1} -> {punycode.convert(str1)}")

print(f"{str2} -> {punycode.convert(str2)}")

print(f"{str3} -> {punycode.convert(str3)}")



# 僕だけの.世界 -> xn--08j3a5b142t.xn--rhqv96g

# こっち.みんな -> xn--l8j9flb8a.xn--q9jyb4c

# 日本語.jp -> xn--wgv71a119e.jp



# Punycode domain to Unicode domain

str4 = "xn--n8jub8754b.xn--rhqv96g"

str5 = "xn--28j2af.xn--q9jyb4c"

str6 = "xn--wgv71a119e.jp"

print(f"{str4} -> {punycode.convert(str4)}")

print(f"{str5} -> {punycode.convert(str5)}")

print(f"{str6} -> {punycode.convert(str6)}")



# xn--n8jub8754b.xn--rhqv96g -> 美しい.世界

# xn--28j2af.xn--q9jyb4c -> こっち.みんな

# xn--wgv71a119e.jp -> 日本語.jp

ascii_only option (v0.2.0 or later)

If you don't want to convert a Punycode domain to Unicode when you use convert() function, you can use ascii_only option. (Default: False)

With this option True, convert() will convert only Unicode domains.

# ascii_only option (v0.2.0 or later)

ascii_only = True



# Only Unicode domains will be converted if ascii_only=True

print(f"{str4} -> {punycode.convert(str4, ascii_only)}")

print(f"{str5} -> {punycode.convert(str5, ascii_only)}")

print(f"{str6} -> {punycode.convert(str6, ascii_only)}")



# xn--n8jub8754b.xn--rhqv96g -> xn--n8jub8754b.xn--rhqv96g

# xn--28j2af.xn--q9jyb4c -> xn--28j2af.xn--q9jyb4c

# xn--wgv71a119e.jp -> xn--wgv71a119e.jp

This option is available on 0.2.0 or later version, so if you use v0.1.0, please update punycode.
