I Keep Getting "IndentationError: expected an indented block"

Question

My program is simple, i'm planing on making a console application where you can draw some art using turtle by some commands such as "left_star","left_circle" ext. When I tried to implement updates, it gives me the indentation error for some reason.Can you help me with this problem?

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

Your elif _input=="right_circle": and all consecutive elifs are not aligned with if _input == "left_star":. Remove the unnecessary spaces in front of the elifs.
