📰 Dev.to · Shima Fallah

Learn the difference between Python's 'is' and '==' operators for value comparison and object identity

beginner Published 28 Jul 2026
Action Steps
  1. Compare values using '==' to check for equality
  2. Use 'is' to compare object identities
  3. Test the difference with examples like 'a = [1, 2, 3]; b = [1, 2, 3]; print(a == b); print(a is b)', which demonstrates how '==' returns True but 'is' returns False
  4. Apply this understanding to avoid common pitfalls in Python programming
  5. Practice using 'is' and '==' in different scenarios to solidify your understanding
