问题描述
运行代码时没有错误，但是我认为问题出在turtle.goto函数上。它仅适用于两个正坐标。我似乎找不到与我接近的问题，并且我尝试了所有不同的turtle函数来建立坐标。我不确定我缺少什么或要做什么。
我知道这段代码看起来很草率，但是我是编码的新手，这只是一门大学课程。
import turtle
import time
#Asking for the shape
shape = int(input("Would you like a Square or a Circle? Type 1 for Square or 2 for Circle: "))
#Asking for the (x,y) coordinates
coordinate = int(input("Which option would you like your shape to be drawn in? please enter a number 1-4. 1. top left,2. bottom left,3. top right,4. bottom right: "))
color = int(input("What color would you like your pen to be? Input 1 for red,2 for blue,or 3 for yellow."))
#Executing if statment
if shape == 2:
if color == 1:
turtle.pencolor("red")
turtle.fillcolor("blue")
elif color == 2:
turtle.pencolor("blue")
turtle.fillcolor("yellow")
else:
turtle.pencolor("yellow")
turtle.fillcolor("red")
#Determining pensize due to coordinate and establishing coordinate plane
if coordinate == 1:
turtle.penup()
turtle.postion(-150,150)
turtle.pendown()
Turtle.pensize(3)
turtle.begin_fill()
turtle.circle(50)
turtle.end_fill()

解决方法
负坐标没有问题。缩进不正确。仅当您选择color = 3时才会绘制形状。
这是更新的代码：
import turtle
import time
#Asking for the shape
shape = int(input("Would you like a Square or a Circle? Type 1 for Square or 2 for Circle: "))
#Asking for the (x,y) coordinates
coordinate = int(input("Which option would you like your shape to be drawn in? please enter a number 1-4. 1. top left,2. bottom left,3. top right,4. bottom right: "))
color = int(input("What color would you like your pen to be? Input 1 for red,2 for blue,or 3 for yellow."))
#Executing if statment
if shape == 2:
if color == 1:
turtle.pencolor("red")
turtle.fillcolor("blue")
elif color == 2:
turtle.pencolor("blue")
turtle.fillcolor("yellow")
else:
turtle.pencolor("yellow")
turtle.fillcolor("red")
#Determining pensize due to coordinate and establishing coordinate plane
if coordinate == 1: # shifted left to align with 'if color`
turtle.penup()
turtle.postion(-150,150)
turtle.pendown()
Turtle.pensize(3)
turtle.begin_fill()
turtle.circle(50)
turtle.end_fill()
