single colon 末端结肠
Syntactically, you use quotes (single or double) around the URI string, and a colon to set off the prefix; other characters present no interference.
根据句法,在uri字符串前后使用引号(单引号或双引号),并用冒号将前缀分隔开;对其它字符没有任何规定。
Namespaces are defined with a prefix, delimited by a single: (colon) character.
名称空间被定义为带有一个前缀,中间用一个:(冒号)分隔。
In this case, I join together a sequence of single-character strings contained in a tuple using the colon character.
在本例中,使用冒号将tuple包含的由单个字符构成的字符串序列连接在一起。
