What module do you import if you want to pickle objects?

Short Answer

Expert verified
Answer: The "pickle" module is needed for pickling objects in Python.

Step by step solution

01

Identify the necessary module for pickling objects

To pickle objects in Python, you need to import the "pickle" module.
02

Importing the Pickle module

To use the pickle module, simply add an import statement at the beginning of your Python script. Like this: ``` import pickle ```
03

Pickling an object

After importing the pickle module, you can now pickle an object. Here's an example using a dictionary object: ```python import pickle data = {"key": "value"} # Pickling the dictionary with open("data.pickle", "wb") as f: pickle.dump(data, f) ```
04

Unpickling an object

To load the pickled data, you can use the following code snippet: ```python import pickle # Loading the pickled data with open("data.pickle", "rb") as f: loaded_data = pickle.load(f) print(loaded_data) # Output: {'key': 'value'} ``` Both the pickling and unpickling processes are now demonstrated, showing that the necessary module for this exercise is "pickle".
