# Python max(x)

`max()` is a built-in function in Python 3. It returns the largest item in an iterable or the largest of two or more arguments.

## Arguments
This function takes two or more numbers or any kind of iterable as an argument. While giving an iterable as an argument we must make sure that all the elements in the iterable are of the same type. This means that we cannot pass a list which has both string and integer values stored in it.

When you say numbers, what do you mean? int or float? Or both?

It can also compare between Strings, right?

Yes.
It can take both int and floats and it can even compare them together.
It works for strings too. It checks for lexicographical order.
eg: max('abc', 'abb', 'abc') # returns 'abc'


Valid Arguments:
```python
max(2, 3)
max([1, 2, 3])
max('a', 'b', 'c')
```
Invalid Arguments:
```python
max(2, 'a')
max([1, 2, 3, 'a'])
max([])
```

## Return Value

The largest item in the iterable is returned. If two or more positional arguments are provided, the largest of the positional arguments
is returned. If the iterable is empty and default is not provided, a ValueError is raised.

Done.Please check


## Code Sample

```python
print(max(2, 3)) # Returns 3 as 3 is the largest of the two values
print(max(2, 3, 23)) # Returns 23 as 23 is the largest of all the values

list1 = [1, 2, 4, 5, 54]
print(max(list1)) # Returns 54 as 54 is the largest value in the list

list2 = ['a', 'b', 'c' ]
print(max(list2)) # Returns 'c' as 'c' is the largest in the list in alphabetical order

list3 = [1, 2, 'abc', 'xyz']
print(max(list3)) # Gives TypeError as values in the list are of different type

#Fix the TypeError mentioned above first before moving on to next step

list4 = []
print(max(list4)) # Gives ValueError as the argument is empty
```
