Using conditionals in comprehensions (1)

You've been using list comprehensions to build lists of values, sometimes using operations to create these values.

An interesting mechanism in list comprehensions is that you can also create lists with values that meet only a certain condition. One way of doing this is by using conditionals on iterator variables. In this exercise, you will do exactly that!

Recall from the video that you can apply a conditional statement to test the iterator variable by adding an if statement in the optional predicate expression part after the for statement in the comprehension:

[ output expression for iterator variable in iterable if predicate expression ].

You will use this recipe to write a list comprehension for this exercise. You are given a list of strings fellowship and, using a list comprehension, you will create a list that only includes the members of fellowship that have 7 characters or more.

Exercise instructions

Use member as the iterator variable in the list comprehension. For the conditional, use len() to evaluate the iterator variable. Note that you only want strings with 7 characters or more.

Hands-on interactive exercise

Have a go at this exercise by completing this sample code.

# Create a list of strings: fellowship
fellowship = ['frodo', 'samwise', 'merry', 'aragorn', 'legolas', 'boromir', 'gimli']

# Create list comprehension: new_fellowship
new_fellowship = [____ for ____ in fellowship ____]

# Print the new list
print(new_fellowship)
