Recap - Elements Of Freedom
Part of the Logic & Flow section of Coddy's Python journey — lesson 55 of 78.
Challenge
EasyCreate a function named elements_of_freedom that processes a list of string elements according to specific rules.
Your function should:
- Filter out elements that have fewer than 5 characters
- Convert the remaining elements to uppercase
- Remove any duplicate elements
- Return a list of the unique uppercase elements
Use list operations to efficiently process the data.
Note: Preserve the original order of elements in the list.
Example:
Input: ["apple", "banana", "cherry", "date", "apple", "banana", "grape", "fig"]
Output: ['APPLE', 'BANANA', 'CHERRY', 'GRAPE']Try it yourself
def elements_of_freedom(elements):
# Your solution here
# Step 1: Filter elements with length >= 5
# Step 2: Convert filtered elements to uppercase
# Step 3: Create a list of unique elements
# Step 4: Return the final result
