python sort with lambda code example

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: how to sort a list in python using lambda

data = [("Apples", 5, "20"), ("Pears", 1, "5"), ("Oranges", 6, "10")]

data.sort(key=lambda x:x[0])
print(data)
OUTPUT
[('Apples', 5, '20'), ('Oranges', 6, '10'), ('Pears', 1, '5')]

Example 3: python lambda key 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 4: python sort based off lambda

a = sorted(a, key=lambda x: x.modified, reverse=True)

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])   # sort by age
[('dave', 'B', 10), ('jane', 'B', 12), ('john', 'A', 15)]
