How do I reduce dicts in Python with examples?

In Python, you can reduce dictionaries using several methods, including comprehension, the `functools.reduce()` function, and other techniques that involve aggregation or combining values.

# Example of reducing a dictionary using a dictionary comprehension

# Sample dictionary
sample_dict = {'a': 1, 'b': 2, 'c': 3}

# Reduce the dictionary to sum its values
reduced_dict = {key: value for key, value in sample_dict.items() if value > 1}

print(reduced_dict)  # Output: {'b': 2, 'c': 3}
