How do I create dicts in Python with examples?

In Python, dictionaries are a built-in data type that allows you to store data in key-value pairs. They are defined by enclosing the key-value pairs in curly braces ({}) and separating each pair with a comma. Here are some examples of how to create and use dictionaries in Python.

# Example of creating a dictionary my_dict = { 'name': 'John Doe', 'age': 30, 'city': 'New York' } # Accessing values print(my_dict['name']) # Output: John Doe # Adding a new key-value pair my_dict['occupation'] = 'Software Developer' # Removing a key-value pair del my_dict['age'] # Iterating through a dictionary for key, value in my_dict.items(): print(f"{key}: {value}")
