Vasiliy is showing you the properties of .copy() versus =. Changing a vaule in either set after setting them equal to each other will alter the values in both sets, where as if you copy the set data, they will act as their own objects and changing one value will not affect the copie...
print()函数不支持老print语句的“软空格”特性,例如,在python2.x中,print "A\n", "B"会输出"A\nB\n",而python3.0中,print("A\n", "B")会输出"A\n B\n" 学会渐渐习惯print()吧! 使用2to3源码转换工具时,所有的print语句被自动转换成print()函数调用,对大项目,这是无需争论的。 python3.0使用...

This sets a to 0, b to 4, and *rest to [1, 2, 3]. Dictionary comprehensions: {k: v for k, v in stuff} means the same thing as dict(stuff) but is more flexible. (This is PEP 0274 vindicated. :-) Set literals, e.g. {1, 2}. Note that {} is an empty dictionary; use...
in the same line, the Python interpreter creates a new object, then references the second variable at the same time. If you do it on separate lines, it doesn't "know" that there's already "wtf!" as an object (because "wtf!" is not implicitly interned as per the facts mentioned abov...
