  1. Description of sorting function

Description max()


Python max()


The max() method returns the largest element in an iterable or largest of two or more parameters.

Differnt syntaxes of max() are:
max(iterable, *iterables[,key, default])
max(arg1, arg2, *args[, key])If you want to find the smallest element, use min() method.

max() Parameters


max() has two forms of arguments it can work with:

1. max(iterable, *iterables[, key, default])

• iterable - sequence (tuple, string), collection (set, dictionary) or an iterator object whose largest element is to be found
• *iterables (Optional) - any number of iterables whose largest is to be found
• key (Optional) - key function where the iterables are passed and comparison is performed based on its return value
• default (Optional) - default value if the given iterable is empty

2. max(arg1, arg2, *args[, key])

• arg1 - mandatory first object for comparison (could be number, string or other object)
• arg2 - mandatory second object for comparison (could be number, string or other object)
• *args​ (Optional) - other objects for comparison
• key - key function where each argument is passed, and comparison is performed based on its return value


Return value from max()


The max() method returns:

1. max(iterable, *iterables[, key, default])


CaseKeyDefaultReturn value
Empty iterable No YesNoRaises ValueError exception
Empty iterableYesYesReturns the default value
Single iterable (Not empty)NoNo YesReturns the largest among the iterable
Single iterable (Not empty)YesNo YesPasses each element in the iterable to the key function Returns largest element based on the return value of the key function
Multiple iterable (Not empty)NoNo YesReturns largest among the given iterables
Multiple iterable (Not empty)YesNo YesPasses each iterable to the key function Returns largest iterable based on the return value of the key function


2. max(arg1, arg2, *args[, key])


CaseKeyReturn value
First and second argument passedNo Returns largest among the given arguments
First and second argument passedYesPasses the arguments to the key function Returns largest among the arguments based on the return value of the key function
More than 2 arguments passedNoReturns largest among the given arguments
More than 2 arguments passedYesPasses each arugment to the key function Returns largest among the arguments based on the return value of the key function


Example 1: Find maximum among the given numbers


----------------------------------------------------------------------------------------------------------------
# using max(arg1, arg2, *args)
print('Maximum is:', max(1, 3, 2, 5, 4))

# using max(iterable)
num = [1, 3, 2, 8, 5, 10, 6]
print('Maximum is:', max(num))
-----------------------------------------------------------------------------------------------------------------
When you run the program, the output will be:
Maximum is: 5
Maximum is: 10

Example 2: Find number whose sum of digits is largest using key function


-----------------------------------------------------------------------------------------------------------------------------------------------
def sumDigit(num):
sum = 0
while(num):
sum += num % 10
num = int(num / 10)
return sum

# using max(arg1, arg2, *args, key)
print('Maximum is:', max(100, 321, 267, 59, 40, key=sumDigit))

# using max(iterable, key)
num = [15, 300, 2700, 821, 52, 10, 6]
print('Maximum is:', max(num, key=sumDigit))
------------------------------------------------------------------------------------------------------------------------------------------------
When you run the program, the output will be:
Maximum is: 267
Maximum is: 821

Here, each element in the passed argument (list or argument) is passed to the same function sumDigit().
Based on the return value of the sumDigit(), i.e. sum of the digits, the largest is returned.

Example 3: Find list with maximum length using key function


-------------------------------------------------------------------------------------------------------------------------------------------------
num = [15, 300, 2700, 821]
num1 = [12, 2]
num2 = [34, 567, 78]

# using max(iterable, *iterables, key)
print('Maximum is:', max(num, num1, num2, key=len))
--------------------------------------------------------------------------------------------------------------------------------------------------
When you run the program, the output will be:
Maximum is: [15, 300, 2700, 821]
In this program, each iterable num, num1 and num2 is passed to the built-in method len().
Based on the result, i.e. length of each list, the list with maximum length is returned.
