sort reverse python code example

Example 1: python sort list in reverse order

# there are two types of lists
# returns new list
sorted(list_name, reverse=True)

# changes list in place
list_name.sort(reverse=True)

Example 2: python sort list in reverse

#1 Changes list
list.sort(reverse=True)
#2 Returns sorted list
sorted(list, reverse=True)

Example 3: python sorted descending

sorted_list = sorted(list)					# ascending (default)
sorted_list = sorted(list, reverse=True)    # descending

Example 4: python sort list

# sort() will change the original list into a sorted list
vowels = ['e', 'a', 'u', 'o', 'i']
vowels.sort()
# Output:
# ['a', 'e', 'i', 'o', 'u']

# sorted() will sort the list and return it while keeping the original
sortedVowels = sorted(vowels)
# Output:
# ['a', 'e', 'i', 'o', 'u']

Example 5: python sort

>>> student_tuples = [
...     ('john', 'A', 15),
...     ('jane', 'B', 12),
...     ('dave', 'B', 10),
... ]
>>> sorted(student_tuples, key=lambda student: student[2])   # sort by age
[('dave', 'B', 10), ('jane', 'B', 12), ('john', 'A', 15)]

Example 6: sorted list python

sorted(iterable, key=None, reverse=False)

type(sorted(iterable, key=None, reverse=False)) = list
