sort()

• sort() method = used with lists
• sort() functions = used with iterables

students = ['spongebob', 'sandy', 'patrick', 'squidward', 'mr.krab']
students.sort()
for i in students:
    print(i)
## to reverse
students.sort(reverse=True)

if we use: students = ('spongebob', 'sandy', 'patrick', 'squidward', 'mr.krab') It will throw an error of AttributeError: 'tuple' object has no attribute 'sort' To sort this we need the built in functions:

sorted_students = sorted(students)
for i in sorted_students:
    print(i)

To reverse it we will use :- sorted(students, reverse = True)

Suppose we have list of tuples:

students = [("Squidward", "F", 60), ("Sandy", "A", 33), ("Patrick", "D", 36),("Spongebob", "B", 20), ("Mr. Krab", "C", 78)]
grades = lambda grades:grades[1]
ages = lambda ages:ages[2]
students.sort(key = grades)
for i in students:
    print(i)

students.sort(key = grades, reverse = True)

Now, suppose we have the list of the list:-

students = (("Squidward", "F", 60), ("Sandy", "A", 33), ("Patrick", "D", 36),("Spongebob", "B", 20), ("Mr. Krab", "C", 78))
ages = lambda ages:ages[2]
sorted_students = sorted(students, key=ages)
for i in sorted_students:
    print(i)
