说明:字符串对象的split()只能处理简单的情况,而且不支持多个分隔符,对分隔符周围可能存在的空格也无能为力。 #example.py# #Example of splitting a string on multiple delimiters using a regeximportre#导入正则表达式模块line='asdf fjdk; afed, fjek,asdf, foo'#(a) Splitting on space, comma, and se...
所以,在此处a_string[18:]跟a_string[18:44]的结果是一样的,因为这个串的刚好有44个字符。这种规则存在某种有趣的对称性。在这个由44个字符组成的串中,a_string[:18]会返回前18个字符,而a_string[18:]则会返回除了前18个字符以外字符串的剩余部分。事实上a_string[:n]总是会返回串的前n个字符,而a_...
字符串的下标索引是从0开始的,所以a_string[0:2]会返回原字符串的前两个元素,从a_string[0]开始,直到但不包括a_string[2]。 如果省略了第一个索引值,Python会默认它的值为0。所以a_string[:18]跟a_string[0:18]的效果是一样的,因为从0开始是被Python默认的。 同样地,如果第2个索引值是原字符串的长...

There.split()function takes a regular expression pattern as its first argument and the target string as its second argument. You can use this function to split strings based on complex criteria, such as multiple, inconsistently used delimiters: ...
Write a Python program to split a string with multiple delimiters. Note : A delimiter is a sequence of one or more characters used to specify the boundary between separate, independent regions in plain text or other data streams. An example of a delimiter is the comma character, which acts ...
