which results in the continuous repetition of the string as many times as the number indicates. Also, if we want to find out thelengthof the string, we simply have to use thelen() function as shown in the example below:
So, again, we first tokenize the string into words or sentences. Then use the len() function to find the number of words or sentences in the string. How to Find the Number of Words in a String We first find the number of words in a string. This requires us to tokenize ...
Return a list of the words in the string, using sep as the delimiter string. sep The delimiter according which to split the string. None (the default value) means split according to any whitespace, and discard empty strings from the result. maxsplit Maximum number of splits to do. -1 (...

split) Help on built-in function split: split(...) S.split([sep [,maxsplit]]) -> list of strings #sep为分隔符,默认为空格 最大分隔次数 Return a list of the words in the string S, using sep as the delimiter string. If maxsplit is given, at most maxsplit splits are done. If ...
Concatenate any number of strings. The string whose method is called is inserted in between each given string. The result is returned as a new string. Example: '.'.join(['ab', 'pq', 'rs']) -> 'ab.pq.rs' 连接任意数量的字符串。
即便假借特例的实用性之名,也不可违背这些规则(这些规则至高无上) Errors should never pass silently. Unless explicitly silenced. # 不要包容所有错误,除非你确定需要这样做(精准地捕获异常,不写except:pass风格的代码) In the face of ambiguity, refuse the temptation to guess. # 当存在多种可能,不要尝试...
