-# PART 2：编程
-
-## 1) 游乐园身高/年龄判定（最终程序）
-
-```python
-# Amusement park eligibility checker
-age = int(input("Enter your age: "))
-
-if age >= 9:
-    height = float(input("Enter your height in cm: "))
-    if height > 130:
-        print("You may go on this ride!")
-    else:
-        print("You are too short for this ride.")
-else:
-    print("You are too young for this ride.")
-```
-
-## 2) 找错并修正（4处错误已修）
-
-原代码中的问题：
-
-* `=>` 应为 `>=`（语法错误）
-* `else if` 应为 `elif`（语法错误）
-* 将整数与字符串比较：`userScore > "600"` 应与整数比较（类型错误）
-* 打印时建议规范金额格式（逻辑/输出规范改进）
-
-修正后的完整代码：
-
-```python
-IDEAL_CREDIT_SCORE = 720
-
-userScore = int(input("Please enter your credit score: "))
-housePrice = float(input("Please enter the price of the house: "))
-
-if userScore >= IDEAL_CREDIT_SCORE:
-    downPayment = 0.10 * housePrice
-elif userScore < IDEAL_CREDIT_SCORE and userScore > 600:
-    downPayment = 0.20 * housePrice
-else:
-    downPayment = 0.30 * housePrice
-
-print("Your down payment is: ${:.2f}".format(downPayment))
-```

-需要的话我也可以给你一些快速测试用例，帮你验证输出是否符合预期。
