The sorted function
The sorted function returns a sorted list of iterables - a list, a tuple, a set, a dictionary. By default, the function sorts the list elements alphabetically or in ascending order.
The first parameter specifies the object to be sorted.
The second optional parameter of the method can be reverse, which specifies the sorting direction. By default, it has the value False.
In the third optional parameter, you can specify a callback function with sorting criteria.
Syntax
sorted(object, [list reversal mode], [function for sorting])
Example
Let's sort our list in reverse order:
lst1 = ['c', 'a', 'd', 'b', 'f', 'e']
lst2 = sorted(lst1, reverse=True)
print(lst2)
Result of code execution:
['f', 'e', 'd', 'c', 'b', 'a']
Example
Now let's sort the list of numbers in reverse order:
lst1 = [10, 8, 2, 6, 14]
lst2 = sorted(lst1, reverse=True)
print(lst2)
Result of code execution:
[14, 10, 8, 6, 2]
Example
Let's sort our list of letters without specifying a parameter in the sorted function:
lst1 = ['c', 'a', 'd', 'b', 'f', 'e']
lst2 = sorted(lst1)
print(lst2)
Result of code execution:
['a', 'b', 'c', 'd', 'e', 'f']
Example
Now let's sort the list of numbers:
lst1 = [10, 8, 2, 6, 14]
lst2 = sorted(lst1)
print(lst2)
Result of code execution:
[2, 6, 8, 10, 14]
Example
Let's sort the set:
st = {'a', 'b', 'c', 'd', 'e', 'f'}
lst = sorted(st)
print(lst)
Result of code execution:
['a', 'b', 'c', 'd', 'e', 'f']
Example
Let's sort the tuple:
tpl = ('a', 'b', 'c', 'd', 'e', 'f')
lst = sorted(tpl)
print(lst)
Result of code execution:
['a', 'b', 'c', 'd', 'e', 'f']
Example
Let's sort the dictionary:
dct = {
'6': 'f',
'2': 'b',
'4': 'd',
'3': 'c',
'1': 'a',
'5': 'e'
}
lst = sorted(dct)
print(lst)
After executing the code, the function will return us a sorted list of dictionary keys:
['1', '2', '3', '4', '5', '6']
Example
You can also sort a string using the sorted function:
str = 'dacbfe'
lst = sorted(str)
print(lst)
But after execution we will also get back a sorted list:
['a', 'b', 'c', 'd', 'e', 'f']
