How to move the turtle where I want to go

So I'm trying to complete this question on my programming course, and it involves drawing stuff with the turtle.
Basically, I'm trying to draw a city skyline, so the program needs to read multiple inputs from the user on one line (the heights of the buildings). I can get it to draw a building, but it only uses the last y-value.

from turtle import *
h = input("Heights: ")
y = h.split()
nxc = -200

#Code for the background

fillcolor("darkslategray")
for i in y:
for i in y:
nyc = i
pencolor("black")
pendown()
begin_fill()
goto(nxc, nyc)
right(90)
forward(20)
right(90)
forward(nyc)
right(90)
forward(20)
right(90)
forward(nyc)
end_fill()
nxc = nxc + 20


Help please!

Answer

Take out your second for loop:

from turtle import *
h = input("Heights: ")
y = h.split()
nxc = -200

#Code for the background

fillcolor("darkslategray")
for i in y:
  nyc = i
  pencolor("black")
  pendown()
  begin_fill()
  goto(nxc, nyc)
  right(90)
  forward(20)
  right(90)
  forward(nyc)
  right(90)
  forward(20)
  right(90)
  forward(nyc)
  end_fill()
  nxc = nxc + 20

This second loop will always reach the end, updating nyc each time, before it exits. Thus, for every iteration, nyc will advance to the final value before Python gets to your drawing code.
