Python generating list using for loop, finding maxValue

Question

The question is to write a function called randNumMaxFor(n, maxValue), with a for loop that generates a list of n random numbers between 0 and maxValue. I can get the random list generated with a for loop but I have no clue how to get to the next step. Thanks for any hints or tips.

import random
def randomNumbers(n):    
    #create an empty list
    myList=[]

    #While loop to create new numbers
    for n in range(0,9):
        #create a random integer between 0 and 9, inclusive
        randomNumber=int(random.random()*10)

        #add the random number to the list of random numbers using the append() method
        myList.append(randomNumber)

    return myList

What happens to the n you pass in as a parameter? It's re-used in the for loop. — Open AI - Opting Out

for loop that generates a list of n random numbers between 0 and maxValue

Your loop doesn't iterate from 0 to n. Replace with this:

for i in range(0,n):

You can use randint() to generate random numbers between 0 to maxValue. It will be something like randint(0, maxValue).

You can then sort the list and return the last value which will be the max value

return sorted(myList)[len(myList) - 1]

import random
def randNumMaxFor(n, maxValue):
    ret = []
    for i in range(n):
        ret.append(random.random() * maxValue)
    return ret

>>> randNumMaxFor(5, 100)
[26.72290088458923,

you can use a list comprehension here: return [random.random() * maxValue for _ in range(n)]

Yes, I just assumed it was a homework task and used more simple syntax.
