## Python - max() function

max() is an in-built function in Python, which may take N number of arguments and returns maximum value of its arguments.

For example, if we provide 3 arguments with the values 20, 10 and 30. max() will return 30 as it is the maximum value among these 3 arguments.

Syntax:

`max(arg1, arg2, arg3, ...)`

Here, arg1, arg2 and arg3 are the arguments which may integer, string etc.

Example:

```    Input arguments are: 20, 10, 30
Output: 30
Because 10 is the maximum argument here.

Input arguments are: “ABC”, “PQR”, “Hello”
Output: “PQR”
Because “ABC” is the maximum argument according
to its length and alphabetically sequences.
```

Source code:

```#Simple example to get max value
#from given arguments

#this will print 30
print "max(20, 10, 30) : ", max(20, 10, 30)
#this will print PQR
print "max('ABC', 'PQR', 'HELLO') : ", max('ABC', 'PQR', 'HELLO')
```

Output

```max(20, 10, 30) :  30
max('ABC', 'PQR', 'HELLO') :  PQR
```

### Finding largest/maximum alphabet from given string

Yes! It can also be used to get the alphabet of maximum ASCII value from given string.

Syntax:

`max(string)`

In this case, string is an argument. Here, max() will return maximum/largest alphabet which has highest ASCII value.

Source code:

```#program to get maximum/largest
#character from given string

#this will return 'o'
print "max('Hello') : ", max('Hello')
#this will return 'O'
print "max('HELLO') : ", max('HELLO')
#this will return 'o'
print "max('hello') : ", max('hello')
```

Output

```max('Hello') :  o
max('HELLO') :  O
max('hello') :  o
```
