Flask中引入了jinja2模板引擎，可以显示动态数据、数据过滤、语句控制、模板继承和引用等。
实战实例
app.py
from flask import Flask,render_template
app = Flask(__name__)
@app.route('/')
def index():
LibraryName="National Library"
visitor={
"name":"Jack",
"storey":"Computer"
}
categoryName=["Python","Linux","Flask"]
return render_template("index.html",LibraryName=LibraryName,visitor=visitor,categoryName=categoryName)
if __name__ == '__main__':
app.run(host='0.0.0.0',port=8000,debug=True)
View Code
index.html
mkdir templates && cd templates
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>index</title>
</head>
<body>
{# National Library #}
