23.7. Chapter Assessment¶
Write code to assign to the variable
map_testing all the elements in lst_check while adding the string “Fruit: ” to the beginning of each element using mapping.
Below, we have provided a list of strings called
countries. Use filter to produce a list called
b_countries that only contains the strings from
countries that begin with B.
Below, we have provided a list of tuples that contain the names of Game of Thrones characters. Using list comprehension, create a list of strings called
first_names that contains only the first names of everyone in the original list.
Use list comprehension to create a list called
lst2 that doubles each element in the list,
Below, we have provided a list of tuples that contain students’ names and their final grades in PYTHON 101. Using list comprehension, create a new list
passed that contains the names of students who passed the class (had a final grade of 70 or greater).
Write code using zip and filter so that these lists (l1 and l2) are combined into one big list and assigned to the variable
opposites if they are both longer than 3 characters each.
Below, we have provided a
species list and a
population list. Use zip to combine these lists into one list of tuples called
pop_info. From this list, create a new list called
endangered that contains the names of species whose populations are below 2500.
