Flask-for循环遍历

//for循环遍历列表和字典：
	//字典的遍历语法和python一样，可以使用items()、kyes()、values()、iteritems()、iterkeys()、itervalues()
from flask import Flask,render_template
app=Flask(__name__)

@app.route('/')
def index():
	user={
		'username':'张三',
		'age':18
	}
	websites=['baidu.com','google.com']
	return render_template('index.html',user=user,websites=websites)

if __name__=='__main__':
	app.run(debug=True)
------------------------------------------
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    {% for k,v in user.items() %}
        <P>{{ k }}:{{ v }}</P>
    {% endfor %}

    {% for websites in websites %}
        <p>{{ websites }}</p>
    {% endfor %}

</body>

			'price': 155
		},
		{
			'name': '水浒传',
			'author': '施耐庵',
			'price': 333
		}
	]
	return render_template('index.html',books=books)

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

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<table>
    <thead>
        <th>书名</th>
        <th>作者</th>
        <th>价格</th>
