So, the complete code takes a string, filters out non-alphabetic characters, converts the remaining characters

5 Dictionary Comprehensions:
Dictionary comprehensions allow you to create dictionaries. They use key-value pair expressions.

TASK 7: Original list of fruits and their lengths
# Original list of fruits and their lengths

fruits = [‘apple’, ‘banana’, ‘orange’, ‘kiwi’, ‘grape’]
fruit_lengths = {fruit: len(fruit) for fruit in fruits}
# Print the original list
print(“Original List of Fruits:”, fruits)
# Print the dictionary created using a comprehension

print(“Dictionary of Fruit Lengths:”, fruit_lengths)
Explanation:
1 fruits = [‘apple’, ‘banana’, ‘orange’, ‘kiwi’, ‘grape’]: Initializes a list of fruits.
2 fruit_lengths = {fruit: len(fruit) for fruit in fruits}:
• This is a dictionary comprehension.

• for fruit in fruits: Iterates over each fruit in the list.
• {fruit: len(fruit)}: Creates a key-value pair in the dictionary, where the key is the fruit, and the value is the
length of the fruit.

3 print(“Original List of Fruits:”, fruits): Prints the original list of fruits.
4 print(“Dictionary of Fruit Lengths:”, fruit_lengths): Prints the dictionary created using the comprehension.
Output:

TASK 8: Temperatures in Celsius
# Original list of temperatures in Celsius

temperatures_celsius = {‘city1’: 25, ‘city2’: 30, ‘city3’: 22, ‘city4’: 18}
# Dictionary comprehension to convert temperatures to Fahrenheit
temperatures_fahrenheit = {city: (temp * 9/5) + 32 for city, temp in temperatures_celsius.items()}
# Print the original temperatures
print(“Original Temperatures (Celsius):”, temperatures_celsius)
