我们可以使用Mermaid语法来绘制一个简单的类图,以帮助理解代码的结构。 TextAnalyzer- text: string- words: list+__init__(text: string)+split_into_words() : list+find_longest_word() : string+print_longest_word() 上面的类图显示了一个名为TextAnalyzer的类,它具有一些属性和方法来处理文本并找到最长的单词。 甘特图 我们可以使用Mermaid语法来绘制一个简单...

The split methods cut a string into parts based on the given separator parameter. With the optional second parameter we can control how many times the string is cut. str.split([sep[, maxsplit]]) Thestr.splitmethod returns a list of the words in the string, separated by the delimiter str...
How to Split a String in Python In this quiz, you'll test your understanding of Python's .split() method. This method is useful for text-processing and data parsing tasks, allowing you to divide a string into a list of substrings based on a specified delimiter.How...
'stRINg lEArn ' >>> >>> str.rjust(20) #str右对齐 ' stRINg lEArn' >>> >>> str.zfill(20) #str右对齐,左边填充0 '00000000stRINg lEArn' 大小写转换 >>> str='stRINg lEArn' >>> >>> str.upper() #转大写 'STRING LEARN' >>> ...
Python string.split 语法 使用string.split的语法如下: string.split([separator[, maxsplit]]) 说明:separator 是分隔符字符串 如果指定了maxsplit,则最多完成maxsplit分割(因此,列表最多包含maxsplit + 1个元素) 如果没有指定maxsplit或-1,那么拆分的数量就没有限制(所有可能的拆分都进行了)。
Lastly, an important application of strings is thesplitmethod, which returns a list of all the words in the initial string and it automatically splits by any white space. It can optionally take a parameter and split the strings by another character, like a comma or a dot ...
text.split()- splits the string into a list of substrings at each space character. grocery.split(', ')- splits the string into a list of substrings at each comma and space character. grocery.split(':')- since there are no colons in the string,split()does not split the string. ...
在本章中,你将了解所有这些以及更多。然后,您将完成两个不同的编程项目:一个存储多个文本字符串的简单剪贴板和一个自动完成格式化文本片段的枯燥工作的程序。 使用字符串 让我们看看 Python 允许你在代码中编写、打印和访问字符串的一些方法。 字符串字面值 ...
