Let's pickle our first set of data consisting of:

• a nested dictionary carrying some information about currencies;
• a list containing a string, an integer, and a list.

When you run the code presented in the right pane, a new file should be created. Remember to run the code locally.

The code starts with the import statement responsible for loading the pickle module:

Later you can see that the file handle 'file_out' is associated with the file opened for writing in binary mode. It’s important to open the file in binary mode as we are dumping data as a stream of bytes.

Now it’s time to persist the first object with the dump() function. This function expects an object to be persisted and a file handle.

And the second object is persisted in the same way:

In this result, we have created a file that retains the pickled objects.
