'builtin_function_or_method' object has no attribute 'choice'

from random import random ,choices
from turtle import Turtle ,Screen
p=Turtle()
p.color("red")
n=(1,2,3,4)
for f in range(0,50,+1):
    n=["1","2","3","4"]
    c=random.choice(n)
    if c==1:
        p.forward(20)
        if c==2:
            p.backward(20)
            if c==3:
                p.up
                p.forward(20)
                if c==4:
                    p.down
                    p.forward

The random.choice function raises the following error:

'builtin_function_or_method' object has no attribute 'choice'

Why does it raise the error and how can I solve the problem?
