Python Adopts Standard Lock File Format for Reproducible Installs
Python has adopted a standardized lock file format to improve reproducibility, security, and tool interoperability across the packaging ecosystem.
A tiny, secure, URL-friendly, unique string ID generator for Python.
Install Nano ID using pip:
pip install nanoid
The main module uses URL-friendly symbols (A-Za-z0-9_-) and returns an ID with 21 characters (to have a collision probability similar to UUID v4).
from nanoid import generate
generate() # => NDzkGoTCdRcaRyt7GOepg
Symbols -,.()
are not encoded in the URL. If used at the end of a link they could be identified as a punctuation symbol.
If you want to reduce ID length (and increase collisions probability), you can pass the length as an argument.
from nanoid import generate
generate(size=10) # => "IRFa-VaY2b"
Don’t forget to check the safety of your ID length in ID collision probability calculator.
If you want to change the ID's alphabet or length you can use the internal generate module.
from nanoid import generate
generate('1234567890abcdef', 10) # => "4f9zd13a42"
Non-secure API is also available:
from nanoid import non_secure_generate
non_secure_generate('1234567890abcdef', 10)
