40岁重启人生学Python，第一次用flask做了一个小学四年级的数学试卷-优快云博客

我使用 Python 的 Flask 框架来创建了小学四年级的数学试卷。以下是相应的代码：

from flask import Flask, render_template_string
import random

app = Flask(__name__)


# 生成加法题目
def generate_addition_questions(num_questions):
    questions = []
    for _ in range(num_questions):
        num1 = random.randint(1, 100)
        num2 = random.randint(1, 100)
        question = f"{num1} + {num2} = "
        answer = num1 + num2
        questions.append((question, answer))
    return questions


# 生成减法题目
def generate_subtraction_questions(num_questions):
    questions = []
    for _ in range(num_questions):
        num1 = random.randint(1, 100)
        num2 = random.randint(1, num1)
        question = f"{num1} - {num2} = "
        answer = num1 - num2
        questions.append((question, answer))
    return questions


# 生成乘法题目
def generate_multiplication_questions(num_questions):
    questions = []
    for _ in range(num_questions):
        num1 = random.randint(1, 10)
        num2 = random.randint(1, 10)
        question = f"{num1} × {num2} = "
        answer = num1 * num2
        questions.append((question, answer))
    return questions


# 生成除法题目
def generate_division_questions(num_questions):
    questions = []
    for _ in range(num_questions):
        num2 = random.randint(1, 10)
        answer = random.randint(1, 10)
        num1 = num2 * answer
        question = f"{num1} ÷ {num2} = "
        questions.append((question, answer))
    return questions


@app.route('/')
def math_paper():
    # 每种类型题目的数量
    num_addition = 5
    num_subtraction = 5
    num_multiplication = 5
    num_division = 5

    # 生成所有题目
    addition_questions = generate_addition_questions(num_addition)
    subtraction_questions = generate_subtraction_questions(num_subtraction)
    multiplication_questions = generate_multiplication_questions(num_multiplication)
    division_questions = generate_division_questions(num_division)

    # 合并所有题目
    all_questions = addition_questions + subtraction_questions + multiplication_questions + division_questions
    random.shuffle(all_questions)

    # 生成 HTML 内容
    html = """
    <!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>小学四年级数学试卷</title>
    </head>
    <body>
        <h1>小学四年级数学试卷</h1>
        <ol>
    """
    for i, (question, _) in enumerate(all_questions, start=1):
        html += f"<li>{question}</li>"
    html += """
        </ol>
    </body>
    </html>
    """
    return render_template_string(html)


if __name__ == '__main__':
    app.run(debug=True)

此代码包含以下部分：

1. 定义四个函数，分别用于生成加法、减法、乘法和除法题目。

2. 定义一个 Flask 路由，生成各种类型的题目，将它们合并并打乱顺序。

3. 生成一个 HTML 页面，其中包含试卷的题目。你可以将上述代码保存为 `math_paper.py`，然后在终端中运行以下命令：
