In previous part we have defined new python set. But defining the set is not enough for real world problems. We will need to add more items into set. We can add new item into set by usingaddfunction and providing the item as parameter to this function. 在上一部分中,我们定义了新的pyth...
(2)).__add__(3) and for 1 - 2 * 3, * has higher priority than -, so it's 1 - (2 * 3) or in python: 1.__sub__(2.__mul__(3)) no operators are changeable, just the priorities or having same result as another just as (1 - 2) + 3 has the same result as 1 -...

OrderedSets implement the union (|), intersection (&), and difference (-) operators like sets do. >>> letters |= OrderedSet('shazam') >>> letters OrderedSet(['a', 'b', 'r', 'c', 'd', 'x', 's', 'h', 'z', 'm']) >>> letters & set('aeiou') OrderedSet(['a'])...

Okay, that was the point of this post: to describe the difference between the short and long operators and introduce the intuition that the longer forms are stricter. The rest of this post will dig into some other oddities and notes about and and or....
An update primitive is obviously something logic but common sense dictates that such a method is mostly used by manual operators working with a judgmental trading approach. 更新原语显然是逻辑上的东西,但常识表明,这种方法主要由从事判断性交易方法的手工操作人员使用。 For order execution logic the followi...
