# 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。
