Filter() and lambda functions
In the previous exercise, you used lambda functions to anonymously embed an operation within map(). You will practice this again in this exercise by using a lambda function with filter(), which may be new to you! The function filter() offers a way to filter out elements from a list that don't satisfy certain criteria.
Your goal in this exercise is to use filter() to create, from an input list of strings, a new list that contains only strings that have more than 6 characters.

Istruzioni dell'esercizio
- In the
filter()call, pass a lambda function and the list of strings,fellowship. The lambda function should check if the number of characters in a stringmemberis greater than 6; use thelen()function to do this. Assign the resulting filter object toresult. - Convert
resultto a list and print out the list.

# Create a list of strings: fellowship
fellowship = ['frodo', 'samwise', 'merry', 'pippin', 'aragorn', 'boromir', 'legolas', 'gimli', 'gandalf']
# Use filter() to apply a lambda function over fellowship: result
____ = filter(____, ____)
# Convert result to a list: result_list
____
# Print result_list
print(result_list)
