List Comprehensions
A list comprehension has the same functionality as dict comprehensions, but is for lists. A list has a specific index for each value. For example, look at the following list of flowers:
PYTHON
1flowers = ["Tulip", "Jasmine", "Rose", "Lili", "Daisy"]If you wanted to create a new list that contains new flowers, you could use a comprehension instead of a loop. The list comprehension has the following syntax:
PYTHON
1list_name = [expression for variable in old_list condition]Let's create a new list using the flowers one:
PYTHON
1new_flowers = ["new" + flower for flower in flowers]The output will be a new list as follows:
PYTHON
1["newTulip", "newJasmine", "newRose", "newLili", "newDaisy"]xxxxxxxxxxflowers = ["Tulip", "Jasmine", "Rose", "Lili", "Daisy"]new_flowers = ["new" + flower for flower in flowers]print(new_flowers)OUTPUT
