Certainly! In Python, when you assign one variable to another, you are creating a reference to the same object in memory. If you want to create a new object with the same values as an existing object without referencing the original object, you need to perform a copy operation. There are several ways to achieve this in Python, and I'll show you a few methods with code examples.
The copy module in Python provides the copy() method, which creates a shallow copy of an object. This means that while the top-level object is duplicated, the inner objects (like lists or other mutable types) are still referenced.
Output:
If your object contains nested objects and you want to create a fully independent copy, you can use the deepcopy() method from the copy module.
Output:
For simple objects like lists or strings, you can use slicing to create a shallow copy.
Output:
Choose the method that best fits your use case based on the complexity of the object you're working with.
