Get a value from a dictionary with a default

Summary

Retrieve a value for a key from a dictionary, returning a provided default when missing.

Problem statement

Write a function get_with_default(dct, key, default) that returns the value associated with key in dct if it exists (even if that value is None). If key is not present in dct, return default. Do not modify the input dictionary.

Task

Implement a helper that returns dct[key] if present, otherwise returns a default value. If the stored value is None, return None (not the default).

Examples

Input format

A Python expression calling get_with_default(dict, key, default)

Output format

Return the value from the dictionary or the default. The test harness compares str(return_value) (or '' if None).

Constraints

- dct may be empty - Keys and values are general Python objects - Do not print; return the value
