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.

Instructions

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 string member is greater than 6; use the len() function to do this. Assign the resulting filter object to result.
Convert result to a list and print out the list.

#Solution:

# 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
result = filter(lambda member:len(member) > 6, fellowship)

# Convert result to a list: result_list
result_list = list(result)

# Print result_list
print(result_list)
