max() and min() in Python

This article brings you a very interesting and lesser known function of Python, namely max() and min(). Now when compared to their C++ counterpart, which only allows two arguments, that too strictly being float, int or char, these functions are not only limited to 2 elements, but can hold many elements as arguments and also support strings in their arguments, hence allowing to display lexicographically smallest or largest string as well. Detailed functionality are explained below.

max()

This function is used to compute the maximum of the values passed in its argument and lexicographically largest value if strings are passed as arguments.

Syntax : 
max(a,b,c,..)
Parameters : 
a,b,c,.. :  similar type of data.
Return Value : 
Returns the maximum of all the arguments.
Exceptions : 
Returns TypeError when conflicting types are compared.

print (max( 4,12,43.3,19,100 ) )

Maximum of 4,12,43.3,19 and 100 is : 100





 min()



This function is used to compute the minimum of the values passed in its argument and lexicographically smallest value if strings are passed as arguments.


Syntax : 
min(a,b,c,..)
Parameters : 
a,b,c,.. :  similar type of data.
Return Value : 
Returns the minimum of all the arguments.
Exceptions : 
Returns TypeError when conflicting types are compared.

Practical Application




One of the practical application among many are finding lexicographically largest and smallest of Strings i.e String appearing first in dictionary or last.
