# Example of safely indexing a dictionary in Python my_dict = {'a': 1, 'b': 2} # Using .get() to safely access values value_a = my_dict.get('a', 'default_value') # returns 1 value_c = my_dict.get('c', 'default_value') # returns 'default_value' # Using 'in' operator to check for existence if 'b' in my_dict: value_b = my_dict['b'] # safely access since we checked else: value_b = 'default_value'
