我想直接调用嵌套函数,如下所示:
Template('/path/to/file').expect('key').to_be_in('second_key')
Template('/path/to/file').expect('key').to_be('value')
我试过了:
class Template(object):
def __init__(self, path):
self.content = json.load(open(path, 'r'))
def expect(self, a):
def to_be_in(b):
b = self.content[b]
return a in b
def to_be(b):
a = self.content[b]
return a == b
但是我收到以下错误:
Template('~/template.json').expect('template_name').to_be_in('domains')
AttributeError: 'NoneType' object has no attribute 'to_be_in'
如何在Python中实现这一目标?
答案 0 :(得分:3)
您必须返回一个提供function maxtwo_right(a){
var b1 = -Infinity;
var b2 = -Infinity;
for (var i=0; i < a.length; i++) {
// If the current entry is bigger than variable b1
// keep the old value in the variable b2 and set b1 to the
// value of the current entry
if (a[i] > b1) {
b2 = b1;
b1 = a[i];
}
// if the current entry equals b1 set the variable b2 to
// the value of the current entry
else if(a[i] === b1){
b2 = a[i];
}
}
// return the sum of the two variables as requested
return b1 + b2;
}
成员函数的对象(仅限示例):
to_be_in
