**Problem :**

Is there any easy way or function to determine the greatest number in a python list? I could just code it, as I only have three numbers, however it would make the code a lot less redundant if I could tell the greatest with a built in function or something.

Solution :

What about `max()`

```
highest = max(1, 2, 3) # or max([1, 2, 3]) for lists
```

You can use the inbuilt function `max()`

with multiple arguments:

```
print max(1, 2, 3)
```

or a list:

```
list = [1, 2, 3]
print max(list)
```

or in fact anything iterable.

This approach is without using`max()`

function

```
a = [1,2,3,4,6,7,99,88,999]
max_num = 0
for i in a:
if i > max_num:
max_num = i
print(max_num)
```

Also if you want to find the index of the resulting max,

```
print(a.index(max_num))
```

Direct approach by using function max()

max() function returns the item with the highest value, or the item with the highest value in an iterable

Example: when you have to find max on integers/numbers

```
a = (1, 5, 3, 9)
print(max(a))
>> 9
```

Example: when you have string

```
x = max("Mike", "John", "Vicky")
print(x)
>> Vicky
```

It basically returns the name with the highest value, ordered alphabetically.

Use `max()`

```
>>> l = [1, 2, 5]
>>> max(l)
5
>>>
```

`max`

is a builtin function in python, which is used to get max value from a sequence, i.e (list, tuple, set, etc..)

```
print(max([9, 7, 12, 5]))
# prints 12
```

You can actually sort it:

```
sorted(l,reverse=True)
```

```
l = [1, 2, 3]
sort=sorted(l,reverse=True)
print(sort)
```

You get:

```
[3,2,1]
```

But still if want to get the max do:

```
print(sort[0])
```

You get:

```
3
```

if second max:

```
print(sort[1])
```

and so on…

```
#Ask for number input
first = int(raw_input('Please type a number: '))
second = int(raw_input('Please type a number: '))
third = int(raw_input('Please type a number: '))
fourth = int(raw_input('Please type a number: '))
fifth = int(raw_input('Please type a number: '))
sixth = int(raw_input('Please type a number: '))
seventh = int(raw_input('Please type a number: '))
eighth = int(raw_input('Please type a number: '))
ninth = int(raw_input('Please type a number: '))
tenth = int(raw_input('Please type a number: '))
#create a list for variables
sorted_list = [first, second, third, fourth, fifth, sixth, seventh,
eighth, ninth, tenth]
odd_numbers = []
#filter list and add odd numbers to new list
for value in sorted_list:
if value%2 != 0:
odd_numbers.append(value)
print 'The greatest odd number you typed was:', max(odd_numbers)
```
