使用 Environment 来初始化对象，并用它来加载模板，

jinja2支持两种加载模板的方式 

• PackageLoader：包加载器
• FileSystemLoader：文件系统加载器

from jinja2 import Environment, FileSystemLoader
env = Environment(
    loader = FileSystemLoader('/home/templates')
)

template = env.get_template('temp.temp')
content = template.render(
name='John Doe',
love_sports = ["basketall","football"],
is_boy=True
)

print content

[root@jinkang-e2elog app]# cat testabcd.py
from jinja2 import Environment, PackageLoader
env = Environment(loader=PackageLoader('testabcd','templates'))

template = env.get_template('temp.temp')
content = template.render(
name='John Doe',
love_sports = ["basketall","football"],
is_boy=True
)

print content
