# Print the converted temperatures
print(“Temperatures (Fahrenheit):”, temperatures_fahrenheit)
Explanation:

1 Temperatures_celsius = {‘city1’: 25, ‘city2’: 30, ‘city3’: 22, ‘city4’: 18}: Initializes a dictionary with city names as
keys and temperatures in Celsius as values.
2. Temperatures_fahrenheit = {city: (temp * 9/5) + 32 for city, temp in temperatures_celsius.items()}:

• This is a dictionary comprehension.
• For city, temp in temperatures_celsius.items(): Iterates over each city and temperature in the original dictionary.
• {city: (temp * 9/5) + 32}: Creates a new key-value pair in the dictionary, where the key is the city, and the value
is the temperature converted to Fahrenheit.

3 Print(“Original Temperatures (Celsius):”, temperatures_celsius): Prints the original temperatures in Celsius.
4 Print(“Temperatures (Fahrenheit):”, temperatures_fahrenheit): Prints the dictionary of temperatures converted
to Fahrenheit.
