Python standard library: Built-in function sorted (iterable[, key][, reverse])

This function is implemented to sort the iterable of an iterative object . The optional parameter key is a function of the comparison key;Reverse is a Boolean value that indicates whether to reverse-arrange the items in the object.

Example:

#sorted () print (sorted ([5, 2, 3, 1, 4])) print (sorted ({1: ' D ', 2: ' B ', 3: ' B ', 4: ' E ', 5: ' A '}, reverse = True)) print (sorted ("This was a test string from Andrew". Split (), Key=str.lower)) Student_tuples = [        (' John ', ' A ', '),        (' Jane ', ' B ', '), (' Dave ', ' B ', '),        ]print (sorted (Student_tuples, Key=lambda student:student[2])   # sorted by age

The resulting output is as follows:

[1, 2, 3, 4, 5]

[5, 4, 3, 2, 1]

[' A ', ' Andrew ', ' from ', ' was ', ' string ', ' test ', ' this ']

[(' Jane ', ' B ', ' + '), (' John ', ' A ', '), (' Dave ', ' B ', 100)]
