Python Question

Write a Python function that will take a the list of 100 random integers between 0 and 1000 and return the maximum value. (Note: there is a builtin function named max but pretend you cannot use it.)

Here's what I tried:

`import random`

list = []

for i in range(100):

list.append(random.randint(0,1000))

def max(list):

#sort list from least to greatest

answer = list.sort()

#get last item in list (max value)

list.pop()

return max

print (max(list))

As you can see, what I'm confused about is how to correctly use the sort and pop methods to return the max value within the max function. I'm currently getting:

`ParseError: bad input on line 12`

Which is this line:

`list.pop()`

Not sure how to correct this. Thanks.

Answer

`my_list.sort()`

sorts the list itself. If you want to store your sorted list in `answer`

, you should use:

```
answer = sorted(my_list)
```

You can also use a list comprehension to generate your first list as follows:

```
>>> random
>>>
>>> my_list = [random.randint(0, 1000) for i in range(100)]
>>> answer = sorted(my_list)
>>> answer.pop()
996 # This should be different each time
```

Now, your function can be:

```
def max(my_list):
# sort list from least to greatest
answer = sorted(my_list)
# get last item in list (max value)
max = answer.pop()
return max
```

If you still want to use the same list, you can do:

```
my_list.sort()
max = my_list.pop()
```

**Note that:** I prefer to call the list `my_list`

because `list`

is a python keyword.
