我不斷收到“IndentationError：期望一個縮進塊”

Question

我的程序很簡單，我打算制作一個控制台應用程序，您可以在其中通過一些命令（例如“left_star”、“left_circle”ext）使用烏龜繪制一些藝術作品。 當我嘗試實現更新時，由於某種原因它給了我縮進錯誤。你能幫我解決這個問題嗎？

import turtle
import random
turtle.color('green', 'red')
turtle.begin_fill()
print(" ")
print("right_star: makes a right star.             ")
print(" ")
print("left_star: makes a star on the left.        ")
print(" ")
print("right_circle: makes a circle on the right.  ")
print(" ")
print("left_circle: makes a circle on the left side")
print(" ")
_input = input("What shape do you want to make? type 'help' if you want help: ")


turtle.Turtle()
print(turtle.pos())
if _input == "left_star":
    i = 0
    while  i != 10:
        turtle.forward(200)
        turtle.left(200)
        i += 1
        if  i > 9:
        #_input2 = input("What shape do you want to make? type 'help' if you want help: ")                      
    elif _input=="right_circle":
        while True:
            turtle.forward(70)   
            turtle.right(70)                                            
            _input2 = input("What shape do you want to make? type 'help' if you want help: ")               
    else _input == "right_star":
        while True:
            turtle.right(200)
            turtle.forward(200)
        while True:
            _input2 = input("What shape do you want to make? type 'help' if you want help: ") 
    elif _input == "left_circle":
        while True:
            turtle.left(70)    
            turtle.forward(70)
    elif _input == "help":
        print("right_star: makes a right star.             ")
        print("left_star: makes a star on the left.        ")
        print("right_circle: makes a circle on the right.  ")
        print("left_circle: makes a circle on the left side")
        print("PLEASE RESTART THE APPLICATION!'python opt.py'")

Answer 1

你的elif _input=="right_circle":和所有連續的elif都沒有與if _input == "left_star":對齊。 刪除elif前面不必要的空格。
