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']

sort in python

Python .sort() / .sorted()
.sort() Sort modifies the list directly.
names = ["Xander", "Buffy", "Angel", "Willow", "Giles"]
names.sort()
print(names)
# ['Angel', 'Buffy', 'Giles', 'Willow', 'Xander']

.sort() also provides us the option to go in reverse easily. 
Instead of sorting in ascending order, we can do so in descending order.
names = ["Xander", "Buffy", "Angel", "Willow", "Giles"]
names.sort(reverse=True)
print(names)
# ['Xander', 'Willow', 'Giles', 'Buffy', 'Angel']

.sorted()  generates a new list instead of modifying 
one that already exists.

names = ["Xander", "Buffy", "Angel", "Willow", "Giles"]
sorted_names = sorted(names)
print(sorted_names)
# ['Angel', 'Buffy', 'Giles', 'Willow', 'Xander']
