What is the difference between python list and tuple?
Article Introduction：The core difference between list and tuple is variability: 1.list is mutable, supporting modification, addition and removal of elements; 2.tuple is immutable, and content cannot be changed after creation. For example, modifying the list element or using the append() method is legal, and doing the same operation on the tuple will throw an error. Syntactically, list uses brackets[], and tuple uses brackets() or comma-separated definitions. In terms of performance, tuple is faster, suitable for large-scale reading operations and fixed data scenarios such as coordinate points. In addition, tuple can be used as a key to a dictionary, while list cannot. Therefore, when data is frequently changed, use list and tuple when data is ensured.

Python List vs Tuple Performance Comparison
Article Introduction：The performance differences between list and tuple are mainly reflected in variability, creation efficiency and usage scenarios. 1. Because the tuple is immutable, the memory is more compact and the access is faster, and it is suitable for read-only data; while the list requires dynamic memory adjustment, which brings additional overhead. 2. Creating tuples is usually faster than lists, especially when creating frequently or large amounts of data, the performance advantages are obvious. 3. Suggestion: Use tuple when the data remains unchanged and high performance is required, such as as a dictionary key or storage configuration item; use list when adding, deleting, or when elements change frequently.

Difference between Python list and tuple
Article Introduction：The main difference between a list and a tuple is mutability, where a list is mutable while a tuple is immutable. 1. Use square brackets for lists, and use round brackets for tuples; 2. Because tuples cannot be safer and faster, they are suitable for fixed data such as coordinates or configuration values; 3. Tuples can be used for dictionary keys, but lists cannot; 4. If you need to modify the data frequently, you should choose a list, and if the data remains unchanged and you pursue performance, you should choose a tuple; 5. Tuples are slightly better than lists in memory, and are suitable for functions that return multiple values ??to ensure consistency. When choosing, it should be decided based on whether the data needs to be changed.

What are the key differences between Python's list and tuple data structures, and when should each be used?
Article Introduction：The main differences between list and tuple in Python are variability, performance and usage scenarios. 1. List is variable, suitable for storing data that needs to be frequently modified; tuple is immutable, suitable for storing fixed data. 2. Tuple is lighter than list and has faster access, suitable for read-only scenarios. 3. Tuple can be used as a dictionary key, list cannot be hashed and cannot be used as a dictionary key. Select to use list or tuple based on whether the data needs to be modified, performance requirements, and whether it is necessary to be used as a dictionary key.
