【问题描述】：

所以我正在开一家太阳镜店。这是我的代码：

# Sun_Glasses_Shop             

import turtle
import random
from random import randint

def build_glasses() :
    crim = turtle.Turtle()
    colors = ['red', 'blue', 'green', 'yellow', 'plum', 'sienna']

crim.color(random.choice(colors), random.choice(colors))
randpos = randint(-100, 100)
crim.width(2)

crim.penup()
crim.setposition(randpos, randpos)
crim.pendown()

# Making First Box 

crim.begin_fill()
for x in range(4):
    crim.forward(50)
    crim.right(90)

crim.end_fill()
crim.forward(50)
crim.right(90)
crim.forward(5)
crim.left(90)
crim.forward(50)
crim.left(90)
crim.forward(5)
crim.right(90)
crim.begin_fill()

# Making Second Box 

for x in range(4):
    crim.forward(50)
    crim.right(90)
crim.end_fill()

print("Welcome to the glasses shop, would you like some?")
A1 = str(input())
if A1 == "yes" or A1 == "Yes" :
    A1 = str(input())    print("Okay, coming right up!")
    build_glasses()
else :
    print("I dont understand try asking me later, bye!")

但是当我运行代码时，它会在模块中打印出来：

Welcome to the glasses shop, would you like some?
yes

Okay, coming right up!

【解决方案1】：

这里是固定代码（你有一个缩进错误）：

import turtle
import random
from random import randint

def build_glasses() :
    crim = turtle.Turtle()
    colors = ['red', 'blue', 'green', 'yellow', 'plum', 'sienna']

    crim.color(random.choice(colors), random.choice(colors))
    randpos = randint(-100, 100)
    crim.width(2)

    crim.penup()
    crim.setposition(randpos, randpos)
    crim.pendown()

    # Making First Box 

    crim.begin_fill()
    for x in range(4):
        crim.forward(50)
        crim.right(90)

    crim.end_fill()
    crim.forward(50)
    crim.right(90)
    crim.forward(5)
    crim.left(90)
    crim.forward(50)
    crim.left(90)
    crim.forward(5)
    crim.right(90)
    crim.begin_fill()

    # Making Second Box 

    for x in range(4):
        crim.forward(50)
        crim.right(90)
    crim.end_fill()

print("Welcome to the glasses shop, would you like some?")
A1 = str(input())
if A1 == "yes" or A1 == "Yes" :
    print("Okay, coming right up!")
    build_glasses()
else :
    print("I dont understand try asking me later, bye!")

输出：

Welcome to the glasses shop, would you like some?
yes
Okay, coming right up!
