1. 简单的猜数字游戏：随机生成一个1到100之间的数字，让用户猜测，如果猜大了或猜小了，给出提示。

```python import random

number_to_guess = random.randint(1, 100) guess = None

while guess!= number_to_guess: guess = int(input("Guess a number between 1 and 100: ")) if guess < number_to_guess: print("Too low!") elif guess > number_to_guess: print("Too high!")

print(f"Congratulations! You guessed the number {number_to_guess}.")

```

2. BMI计算器：用户输入身高和体重，程序计算并输出BMI指数。

```python height = float(input("Enter your height in meters: ")) weight = float(input("Enter your weight in kilograms: "))

bmi = weight / (height 2)

print(f"Your BMI is {bmi:.2f}.") ```

3. 简单的日记应用：用户可以输入他们的日记条目，这些条目将被保存在文本文件中。

```python def write_diary(): diary_entry = input("Enter your diary entry: ") with open('diary.txt', 'a') as file: file.write(diary_entry + '\n')

write_diary() ```

4. 简单的货币转换器：用户输入货币类型和金额，程序将进行货币转换。

```python def currency_converter(): currency Converter from USD to EUR usd = float(input("Enter amount in USD: ")) rate = 0.91 # current exchange rate eur = usd * rate print(f"{usd} USD is equal to {eur:.2f} EUR.")

currency_converter() ```

5. 简单的数学练习：程序随机生成加减乘除的数学题目，用户输入答案，程序判断答案是否正确。

```python import random

def math_practice(): num1 = random.randint(1, 10) num2 = random.randint(1, 10) operator = random.choice(["+", "-", "*", "/"])

if operator == "+": correct_answer = num1 + num2 elif operator == "-": correct_answer = num1 - num2 elif operator == "*": correct_answer = num1 * num2 else: correct_answer = round(num1 / num2, 2)

user_answer = float(input(f"What is {num1} {operator} {num2}? "))

if user_answer == correct_answer: print("Correct!") else: print(f"Wrong. The correct answer is {correct_answer}.")

math_practice() ```

这些项目都是基础的，随着Python知识的深入，你可以尝试更复杂的项目，比如Web应用开发，数据分析，机器学习等。
