Highest and lowest function

Question

In this little assignment you are given a string of space separated numbers, and have to return the highest and lowest number.

Example:
high_and_low("1 2 3 4 5") # return "5 1"
high_and_low("1 2 -3 4 5") # return "5 -3"

What I have tried:

Python

def high_and_low(numbers):
    li = numbers.split()
    mx = max(li)
    mn = min(li)
    return str(mx)+" "+str(mn)
print(high_and_low("4 5 29 54 4 0 -214 542 -64 1 -3 6 -6"))

I am getting 6 -214

Solution 3

def high_and_low(numbers):
    numbers = numbers.split(" ")
    numbers = list(map(int, numbers))
    # so every number in numbers will be recognized as an integer
    p = max(numbers)
    q = min(numbers)
    return str(p) + str(" ") + str(q)
print(high_and_low("4 5 29 54 4 0 -214 542 -64 1 -3 6 -6"))
# Output will be: 542 -214

def high_and_low(numbers):
    return " ".join(i(numbers.split(), key=int) for i in (max, min))
print(high_and_low("4 5 29 54 4 0 -214 542 -64 1 -3 6 -6"))

In what way is this an improvement on (or even different from) Solution 2?

It is different because I used map function instead for.
If you want improvement, here take this one-liner (though it is not different than 2nd solution. Just better.)

Just a guess: you forgot to convert each element of li to numbers.
numbers is a string, after split, you get a list of strings. Since you want to compare integer values of strings, you need to covert the list of strings to a list of integers.

Why in string "6" is greater than others? How max function works on string. In my opinion it uses the number of charaters in the string but this does seem to be the case here.

Sorted strings are in same order as words in a dictionary.
-24 < -52 < 1 < 11 < 15 < 2 < 25< 2614 < 3 < 33 < 4

Solution 2

def high_and_low(numbers):
    li =[int(x) for x in list1.split(' ')]
    mx = max(li)
    mn = min(li)
    return str(mx)+" "+str(mn)
print(high_and_low("4 5 29 54 4 0 -214 542 -64 1 -3 6 -6"))
