如果你运行上面的代码,你会因为错误使用 continue 字符而收到这个错误。如果我们把它写在前面,那么代码就不会运行。 Python #correctprint("Hello I am python. I have an interseting Line continuation character which is used at the end of line or statment"
匹配对象中有以下几个方法最为重要: >>>m.group()'123'>>>m.start(),m.end() (0,3)>>>m.span() (0,3) group()返回正则匹配的子字符串。start()和end()返回匹配的起始和结束索引。span()在单个元组中返回开始和结束索引。由于match()方法只检查正则是否在字符串的开头匹配,所以start()将始终为零。
In the above example, we have used the\continuation character to break the single statement into 2 lines. You can also notice that we used the \ symbol at the end of the first line to break the line. And if we try to put any other character after it we would receive the Error. Er...
