Answer 1

问题是您尝试实例化模块 context的对象而不是类 Context（请注意资本）。

这样做：

from django.template import Context

html = t.render(Context({'name': name}))

文档中还有example。

Answer 2

context中导入的django.template.context是一个无法调用的模块。

您正在寻找Context课程

from django.template import Context

然后尝试这样：

...
html = t.render(Context({'name': name}))
...

/ hello_template中的TypeError - ＆＃39; module＆＃39;对象不可调用
