“Does Python Intern Strings?” ~ bbaz
Introduction
Python is a popular programming language that allows developers to create powerful and efficient applications. However, one of the concepts that can confuse new developers is interned strings. In this article, we’ll provide a comprehensive guide to interned strings, why they’re important, and how they differ from ordinary strings.
What are Interned Strings?
Interned strings are a special type of string in Python that are stored in a string pool. This means that when two identical strings are created, Python only stores one copy of the string in memory. Any subsequent references to the string will simply point to the existing copy. This can save memory and improve the performance of certain operations.
Interned Strings vs Regular Strings
The main difference between interned strings and regular strings is how they’re stored in memory. Regular strings are stored as separate objects in memory, regardless of whether they have the same value. Interned strings, on the other hand, are stored in a shared pool and only one copy is kept for each distinct value. This can lead to significant differences in memory usage and performance for certain operations.
Why Understanding Interned Strings is Essential
If you’re serious about mastering Python, it’s essential that you understand the concept of interned strings. This is because they play a critical role in the performance and memory usage of your applications. By using interned strings in the right way, you can optimize your code and achieve better results.
Table Comparison
To help illustrate the differences between interned strings and regular strings, let’s compare their performance and memory usage using a simple example:
| Operation | Regular String | Interned String |
|---|---|---|
| Create string | 100 bytes | 100 bytes |
| Create another identical string | 100 bytes | 0 bytes (points to existing string) |
| Compare strings | 100 microseconds | 0 microseconds (compares memory addresses) |
As you can see, using interned strings can significantly reduce memory usage and improve performance for certain operations.

People Also Ask:
1. What are interned strings in Python?
- Interned strings are a feature of Python that allows for string objects to be shared across multiple variables, reducing memory usage and improving performance.
- When a string is created, Python checks if it already exists in memory. If it does, the new variable is pointed to the existing object instead of creating a new one.
- This process is automatic and happens behind the scenes.
2. How do I know if a string is interned in Python?
- You can use the
isoperator to check if two variables point to the same object in memory. - For example,
hello is hellowill returnTruebecause both variables point to the same interned string object. - However,
hello world is hello worldwill not necessarily returnTrue, as longer strings are less likely to be interned.
3. Can I force a string to be interned in Python?
- Yes, you can use the
sys.intern()method to force a string to be interned. - For example,
my_string = sys.intern(hello world)will ensure thatmy_stringpoints to the interned version of hello world if it exists, or intern it if it doesn’t.
4. Are all strings interned in Python?
- No, not all strings are interned in Python.
- Python only interns strings that are created at compile time or runtime, and are composed of ASCII letters, digits and underscores (i.e. valid Python identifiers).
- Longer strings are also less likely to be interned.
5. What are the benefits of using interned strings in Python?
- Interned strings can significantly reduce memory usage and improve performance, especially in applications that use large amounts of string data.
- They can also help to reduce the number of duplicate string objects in memory, which can be particularly useful in multi-threaded applications or when working with large datasets.
