1.简单的渲染页面

# 1.导入flask类
from flask import Flask, render_template

# 2.创建flask实例
app = Flask(__name__)


# 3.创建视图函数，并且指定路由
@app.route("/")
def index():
    # 4.渲染页面,传递参数：单值,序列,映射
    return render_template("index.html", param1="单值", param2=[1, 2, 3], param3={"key01": "value02", "key02": "value02"})


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