Example 1: sorted python lambda
lst = [('candy','30','100'), ('apple','10','200'), ('baby','20','300')]
lst.sort(key=lambda x:x[1])
print(lst)
Example 2: python lambda key sort
>>> 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 based off lambda
a = sorted(a, key=lambda x: x.modified, reverse=True)
Example 4: sorted list python
sorted(iterable, key=None, reverse=False)
type(sorted(iterable, key=None, reverse=False)) = list
Example 5: 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)]
Example 6: python sort
nums = [4,8,5,2,1]
sorted_nums = sorted(nums)
print(sorted_nums)
print(nums)
nums.sort()
print(nums)
