快速上手 Python 框架 FastAPI FastAPI 是一种现代，快速（高性能）的 Web 框架，基于标准Python 类型提示使用 Python 3.6+ 构建 API。 FastAPI 文档 官方文档：https://fastapi.tiangolo.com/ FastAPI 安装 FastAPI 推荐使用 uvicorn 来运行服务，Uvicorn 是基于 uvloop 和 httptools 构建的闪电般快速的 ASGI 服务器。 在终端中执行以下命令： pip install fastapi pip install uvicorn FastAPI 实践 创建一个 .py 文件，并写以下代码 from typing import Optional from fastapi import FastAPI app = FastAPI() @app.get("/api/v1/hw") def read_root(): return {"Hello": "World"} @app.get("api/v1/items/{item_id}") def read_item(item_id: int): return {"item_id": item_id} -
Python抽取分数超过60的学生 print('1111') 示例数据 students = [ {'name': 'Alice', 'score': 78}, {'name': 'Bob', 'score': 56}, {'name': 'Charlie', 'score': 84}, {'name': 'Dave', 'score': 92} ] 这个例子中，filter_students_by_score 函数通过列表推导式（list comprehension）筛选出那些分数超过60的学生记录。 抽取分数超过60的学生 def filter_students_by_score(data): return [student for student in data if student['score'] > 60] filtered_students = filter_students_by_score(students) 打印结果 for student in filtered_students: print(student) -
Python-生成固定时间且间隔为1分随机测试数据Json实例 This is a sample Python script. import random from datetime import datetime, timedelta import json if __name__ == '__main__': print_hi('PyCharm') #### See PyCharm help at https://www.jetbrains.com/help/pycharm/ ### 定义开始和结束时间 start_time = datetime(2024, 9, 9, 14, 00) # 2024年3月1日 8:30 end_time = datetime(2024, 9, 9, 14, 30) # 2024年3月1日 9:30 ### 时间间隔设置为1分 interval = timedelta(minutes=1) ### 生成时间列表 time_list = [start_time + i * interval for i in range((end_time - start_time) // interval)] print(f"随机产生温度参数：") for ind, time in enumerate(time_list): jsonList = {
