**Python max, min Examples**Call the max and min built-in functions to search for the largest and smallest elements in lists.

**Max, min.** In a list, we do not need to search for the largest or smallest element. Instead we use max and min. The maximum or minimum value is returned.

**Argument details.** With 2 arguments, max returns the larger of the two. And min returns the smaller. We can use max and min to compare two variables.

**List example.** Max and min act on iterables. A list is a common iterable. We use max and min on a list with positive and negative integer elements.

List, strings

**Here** Max returns the value 1000, which is larger than all other elements in the list. And min returns negative 100.

**Tip** In all uses, max and min return a single value. If all elements are equal, that value is returned.

Python program that uses max, min

values = [

1, -1,

-2, 0]

*
# Find the max and min elements.
*print(

__max__(values))
print(

__min__(values))

1
-2

**Strings.** Consider the use of max and min on a list of strings. An alphabetic sort is used to test strings. The same comparison is used to sort a list.

**So** The string that is sorted first is the min. And the string that comes last in sorting is the max.

Python program that uses max, min on string list

values = [

"cat",

"bird",

"apple"]

*
# Use max on the list of strings.
*result =

__max__(values)
print(

*"MAX"*, values, result)

*
# Use min.
*result =

__min__(values)
print(

*"MIN"*, values, result)

MAX ['cat', 'bird', 'apple'] cat
MIN ['cat', 'bird', 'apple'] apple

**Two arguments.** A program has two variables. One has a value larger than the other. We can determine the larger value by passing both variables to max.

**Java** This use of max and min is similar to methods like Math.max in Java and Math.Max in C#.

Python program that uses max, min with two arguments

value1 =

*100*
value2 =

*-5**
# Call max with two arguments.
# ... The larger argument is returned.
*maximum =

__max__(value1, value2)
print(

*"MAX"*, maximum)

*
# Call min with two arguments.
*minimum =

__min__(value1, value2)
print(

*"MIN"*, minimum)

*
# If the arguments are equal, max and min return that value.
*print(

*"MAX"*,

__max__(0, 0))
print(

*"MIN"*,

__min__(0, 0))

MAX 100
MIN -5
MAX 0
MIN 0

**A summary.** With max and min, we search iterables for the largest and smallest elements. We can use these built-in functions to compare 2 arguments and return the larger or smaller one.
