Recap
Tuples as return types in functions
Tuples as records
List of tuples
Instruction
Great! Here is another example where we combine list and tuple techniques:
cars_to_sell = [
('Volvo', 18000, 137000),
('BMW', 23000, 80000),
('Opel', 12000, 75000),
('Ford', 14500, 100000)
]
def remove_cars_above_15k(car_list):
for car in car_list[:]:
if car[1] > 15000:
car_list.remove(car)
remove_cars_above_15k(cars_to_sell)
In the above code, we remove cars priced above $15,000. Note that we iterated over a copy of the input list – we used car_list[:] in the for loop – to avoid incorrect results. This is a trick we learned in the previous part.
Exercise
Create a function named remove_sql_specialists(people_list) that, given a list of tuples in the format shown in the template code, removes people whose job titles contain the word "SQL" from the list.
Stuck? Here's a hint!
You can use the in operator to check if a given job title contains the word "SQL":
if 'SQL' in position: ...
