Warnings

gotcha Package is part of a namespace package (twitter.common). Installing multiple twitter-common-* subpackages may cause import conflicts if versions mismatch. ↓

fix Use virtual environments and pin all twitter-common dependencies to same version.

deprecated The library is no longer maintained; Python 3 support is partial and may have edge cases. ↓

fix Consider migrating to standard library or modern alternatives (e.g., six, future, threading).

gotcha import twitter.common.lang does not work; must use from twitter.common.lang import ... ↓

fix Always use explicit from imports.

Imports

Quickstart

Basic usage of twitter.common.lang for compatibility checks and locking.

from twitter.common.lang import compat, Lock

# Check Python version compatibility
print(compat.PY3)  # True if Python 3

# Use a reentrant lock
lock = Lock()
with lock:
    print("Lock acquired")
