1、
Several planets in our solar system are famous for distinctive features. Saturn has its wondrous rings and Jupiter has its famous red spot, while Uranus has its many moons and planets like Mercury have no moons at all. Earth’s main claim to fame is it being the only planet in the solar system with the perfect conditions for human life and a single moon, both of which make it a pretty special place for use to call home. But, there’s a chance that Earth could have another moon hanging out in its orbit for now. CNET reports that Catalina Sky Survey astronomers in Tuscon, AZ has its eyes on an asteroid hanging out in Earth’s gravity. It’s possible that this body of rock could be a mini-moon orbiting our planet, which means Earth would have two moons. That’s pretty cool, right?

The State Council joint prevention and control mechanism 27, held a news conference to introduce the ban and resolutely crack down on illegal work of wildlife markets and trade. State Bureau of Animal and Plant Protection Division of wild grass Deputy Director Wang Weisheng said that since the outbreak, the National Bureau of grass implemented the most stringent wildlife control a series of measures.

The Zen of Python, by Tim Peters Beautiful is better than ugly. Explicit is better than implicit. Simple is better than complex. Complex is better than complicated. Flat is better than nested. Sparse is better than dense. Readability counts. Special cases aren't special enough to break the rules. Although practicality beats purity. Errors should never pass silently. Unless explicitly silenced. In the face of ambiguity, refuse the temptation to guess. There should be one-- and preferably only one --obvious way to do it. Although that way may not be obvious at first unless you're Dutch. Now is better than never. Although never is often better than *right* now. If the implementation is hard to explain, it's a bad idea. If the implementation is easy to explain, it may be a good idea. Namespaces are one honking great idea -- let's do more of those!
