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...
also known as “Python 3000” or “Py3K”, is the first ever intentionally backwards incompatible Python release. There are more changes than in a typical release, and more that are important for all Python users. Nevertheless, after digesting the changes, you’ll find that Python really hasn...

The sections above provide the theoretical background behind geometry in general. While using the ArcGIS API for Python, we primarily work with well-known IDs called as wkid. For instance, the wkid of Web Mercator PCS explained above is 3857. Occasionally, you might see a latestWkid being use...
parentheses are simply a curved symbol that is used in text to indicate additional information, such as a comment or an aside. they are known by many other names, including parentheses, round brackets, curved brackets, and more. when it comes to computers and programming, parentheses often ...
Python also lets you embed a tuple or other type of data structure within a tuple, as in the following example, which includes a tuple as the third value. tuple5 = ('carry', 192, (-89.73773, 18, 'distinct')); Python is, of course, only one programming language. The rules that gov...
