Understanding String Interning in Python Programming

In this video, we’ll explore the concept of string interning in Python and how it optimizes memory usage. You’ll learn why Python automatically interns short strings, how it improves performance by storing identical strings only once in memory, and why strings with the same content might behave differently depending on their length. I’ll demonstrate through examples when the is operator will return True and False when comparing string identities. We’ll also discuss how string interning works for small and long strings, and how you can manually intern a string using Python’s sys module. What You’ll Learn: What is string interning in Python. How Python optimizes memory usage with string interning. Why strings with the same content might not always be the same object in memory. How to manually intern a string in Python using the sys module.
