sort list python based on key code example
Example 1: python sort list
vowels = ['e', 'a', 'u', 'o', 'i']
vowels.sort()
sortedVowels = sorted(vowels)
Example 2: list sort by key python
>>> student_tuples = [
... ('john', 'A', 15),
... ('jane', 'B', 12),
... ('dave', 'B', 10),
... ]
>>> sorted(student_tuples, key=lambda student: student[2])
[('dave', 'B', 10), ('jane', 'B', 12), ('john', 'A', 15)]
Example 3: python sort comparator
sorted("This is a test string from Andrew".split(), key=str.lower)
['a', 'Andrew', 'from', 'is', 'string', 'test', 'This']
sorted(student_tuples, key=lambda student: student[2])
[('dave', 'B', 10), ('jane', 'B', 12), ('john', 'A', 15)]
