Why is only half of my program (3/4 functions) printing in python?-CodePudding

I have a question: I don't understand why my last function isn't going through and printing anything. I tried fixing where I think I might've messed up, but I can't find it. My task is to create function 1 that checks if all the values in a list are unique or not and return true or false, and the second function is the one that generates the random integer list based on user input (function 1 helps with this). After this, I need to find the nth maximum in the list that is requested by the user, which is the part that doesn't seem to be working.

For Example:

If the list has the values 1 3 7 2 15 20 5 18 11 and the user wanted the:

1st Maximum (n = 1) -> It would return 20 (the highest number)

2nd Maximum (n = 2) -> It would return 18 (the second highest number)

3rd Maximum (n = 3) -> It would return 15 (the third highest number)

import random
#check for all unique values in list
def allunique(x):
    unique_or_not= []
    for item in x:
        if item in unique_or_not:
            return False
        unique_or_not.append(item)
    return True

#generate list of random numbers
def list_of_nums(start,end,number_of_values):
    nums= []
#how can I let integer also be a negative value with range??
    for i in range(0,number_of_values):
        nums.append(random.randint(start,end))
    return nums


#main function of inputs and calls list
def main():
    number_of_values= int(input("Please enter the number of values you wish to generate:"))
    start= int(input("Please enter the starting # of the values you wish to generate:"))
    end= int(input("Please enter the ending # of the values you wish to generate:"))
    myList= list_of_nums(start,end, number_of_values)
    print(myList)


#find nth max
def finding_nth_max(nums):
    sorted_list= nums.sorted()
    nthmax= int(input("Please enter the nth maximum you would like to find: "))
    print("The nth maximum is", sorted_list[-nthmax])

 main()

CodePudding user response：

you must add finding_nth_max(your_list_here) function within your main function, for the output of that function to be printed. This must be added after you have called list_of_nums in your main function

CodePudding user response：

you need to call method and nums.sort() does not return anything, it updates the list automatically

def find_nth_max(nums: list):
    nums.sort()
    print(f'provided list: {nums}')
    nthmax= int(input("Please enter the nth maximum you would like to find: "))
    print("The nth maximum is", nums[-nthmax])
find_nth_max([2, 5, 1, 8])
