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...
we have to call it on the string that’ll be used for joining. In this case, we’re using a string with a space in it. The method receives a list of strings and returns one string with each of the strings joined by the initial string. Let’s check its functionality with...
Also, any leading and trailing whitespaces are trimmed before the string is split into a list of words. So the output will remain same for string s = ' Welcome To JournalDev ' too. Let’s look at another example where we have CSV data into a string and we will convert it to the ...

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 ...
split('#', 2) print(words) # ['I', 'love', 'you#so#much'] 编码和解码 Python 中除了字符串str类型外,还有一种表示二进制数据的字节串类型(bytes)。所谓字节串,就是由零个或多个字节组成的有限序列。通过字符串的encode方法,我们可以按照某种编码方式将字符串编码为字节串,我们也可以使用字节串的...
split(", ") print(words) # 输出: ['Hello', 'World!'] sentence = "-".join(words) print(sentence) # 输出: Hello-World! 在数据分析和日志记录中,字符串格式化经常用于生成报告或调试信息。例如,在生成CSV文件时,字符串连接和格式化至关重要: import csv data = [("Alice", 30), ("Bob", 28...
使用join()和split()方法 当您有一个需要连接成一个字符串值的字符串列表时,join()方法很有用。在一个字符串上调用join()方法,传递一个字符串列表,然后返回一个字符串。返回的字符串是传入列表中每个字符串的连接。例如,在交互式 Shell 中输入以下内容: ...
