Certainly! Here's an example code to demonstrate how dictionaries work in Python:

</code>
# Creating a dictionary
person = {"name": "John", "age": 30, "city": "New York"}

# Accessing values in a dictionary
print(person["name"]) # Output: John
print(person["age"]) # Output: 30
print(person["city"]) # Output: New York

# Modifying values in a dictionary
person["age"] = 35
print(person["age"]) # Output: 35

# Adding a new key-value pair to the dictionary
person["country"] = "United States"
print(person) # Output: {'name': 'John', 'age': 35, 'city': 'New York', 'country': 'United States'}

# Removing a key-value pair from the dictionary
del person["city"]
print(person) # Output: {'name': 'John', 'age': 35, 'country': 'United States'}

# Looping through a dictionary
for key in person:
    print(key, ":", person[key])
# Output:
# name : John
# age : 35
# country : United States
