What function do you call to pickle an object?

The function used for pickling an object in Python is `pickle.dump()`. Here's a step-by-step guide: 1. Understanding Pickling: Pickling is the process of converting a Python object into a byte stream that can be saved to a file or sent over a network. This allows you to store and transfer complex Python objects easily. 2. Importing the pickle module: To use the module, you'll need to import it using `import pickle`. 3. Create the object to be pickled: Create the object you'd like to pickle, such as a list, dictionary, or a custom object. 4. Pickling the object using the `dump` function: Use the `pickle.dump()` function to pickle the object. This function takes two arguments: the object to be pickled and the file-like object where the pickled data should be written. Open a file first in 'write binary' mode (e.g., 'data.pkl', 'wb') to write the pickled data to it and then dump the object using `pickle.dump(data, file)`.
