Python Weighted Choice with input list

I need to make a weighted prediction based on the outcomes of this list however there are some problems im running into

Code: 
from random import choices
import statistics
from time import sleep
threecount = 0
fourcount = 0
fivecount = 0
pthreecount = 0
pfourcount = 0
pfivecount = 0
lst = []
print("What did you obtain?")
for plays in range(5):

  listy = ["3", "4", "5"]
  x = int(input("3, 4 or 5 star: "))
  lst.append(x)
  sleep(.5)
 
          

print("List of what you obtained:", lst)
sleep(1)


y = str(statistics.mode(lst))
print("The most common star you got was " + y)
sleep(1)

threecounter = lst.count(3)
print("You obtained a 3 star", threecounter, "times")
sleep(1)

fourcounter = lst.count(4)
print("You obtained a 4 star", fourcounter, "times")
sleep(1)

fivecounter = lst.count(5)
print("You obtained a 5 star", fivecounter, "times")

if input == "3":
    pthreecount = pthreecount + 1
if input == "4":
    pfourcountt = pfourcount + 1
if input == "5":
    pfivecount = pfivecount + 1
x = choices(listy, weights=(pthreecount, pfourcount, pfivecount), k=3)
print(x)

Here's an example of the output of this code:

Code: 
What did you obtain?
3, 4 or 5 star: 3
3, 4 or 5 star: 3
33, 4 or 5 star: 3
33, 4 or 5 star: 3
3, 4 or 5 star: 3
List of what you obtained: [3, 3, 3, 3, 3]
The most common star you got was 3
You obtained a 3 star 5 times
You obtained a 4 star 0 times
You obtained a 5 star 0 times
['5', '5', '5']
Click to expand...

It shouldn't output {'5','5','5'} i want it to output a weighted choice based on how many times each one is chosen. Any advice?

Are you trying to do something like this?

Python: 
# Do the imports
from random import choices
import statistics
# Define a dict to hold the individual counts
counter = {
    '3': 0,
    '4': 0,
    '5': 0
}
# Counter for the while loop
counting = 0
# A list to hold the numbers
numlist = []
# Start the loop
while counting < 5:
    # Using try except for basic error checking. /Only whole numbers can be entered
    try:
        num = int(input('Enter 3, 4 , or 5\n>> '))
    except ValueError:
        print('Only whole numbers are allowed')
    # Passed error checking continue
    else:
        # Using if elif and else for our numbers. if the number entered is anything other than
        # 3, 4, or 5, an error is printed
        if num == 3:
            print('you chose 3')
            counter['3'] += 1
            numlist.append(num)
            counting += 1
        elif num == 4:
            print('you chose 4')
            counter['4'] += 1
            numlist.append(num)
            counting += 1
        elif num == 5:
            print('you chose 5')
            counter['5'] += 1
            numlist.append(num)
            counting += 1
        else:
            print('Choices are: 3, 4, or 5')
            continue
# Print out all data
print(f'List of what you obtained {", ".join(str(n) for n in numlist)}')
print(f'The most common star you got was {statistics.mode(numlist)}')
for key, value in counter.items():
    print(f'You obtained a {key} star {value} times')
print(choices(numlist, weights=[n for n in numlist], k=3))

Output

Code: 
Enter 3, 4 , or 5

Enter 3, 4 , or 5

you chose 3     
Enter 3, 4 , or 5

you chose 3     
Enter 3, 4 , or 5
>> 3
you chose 3
List of what you obtained 3, 3, 3, 3, 3
The most common star you got was 3
You obtained a 3 star 5 times
You obtained a 4 star 0 times
You obtained a 5 star 0 times

YES THIS IS EXACTLY WHAT I WANTED U HAVE NO IDEA HOW GRATEFUL I AMMMM!!! Now onto making a bar chart out of the data..........(is it too much to ask for help on this...perhaps a website where I could copy some code?) BUT THANK UUUU

Not really sure what data you going to plot but, you could give matplotlib a try.

Add to end of above code

Code: 
stars = ['1', '2', '3', '4', '5']
plt.bar(stars, numlist, color=sample(colors, k=len(numlist)))
plt.show()

Thank you for this. It came up with some errors but i managed to get a working barchart!!

Code: 
colors = ['red', 'green', 'blue']
stars = ['3 stars', '4 stars', '5 stars']
y_axis = [counter['3'], counter['4'], counter['5'] ]

plt.bar(stars, y_axis)
plt.title('BarChart')
plt.xlabel('Stars')
plt.ylabel('Number of Times Obtained')
plt.show()
