for example, if we have a text that’s too long to display and we want to show just a portion of it. Or if we want to make an acronym by taking the first letter of each word in a phrase. We can do that through an operation calledstring indexing.This...

for i in 'Hello':print(i)Out:Hello 可以使用for循环解包字符串中的每个字符，并对它们执行各种操作。同样，也可以遍历句子中的每个单词。但是在这种情况下，需要一个额外的步骤来分割句子。sent = 'the sky is blue'# splitting the sentence into wordssent_split = sent.split()# extract each word with ...

string.replace('a', 'b'): 这将用b替换字符串中的所有a 此外,我们可以使用len()方法获取字符串中字符的数量,包括空格: #!/usr/bin/pythona ="Python"b ="Python\n"c ="Python "printlen(a)printlen(b)printlen(c) 您可以在这里阅读更多关于字符串函数的内容:docs.python.org/2/library/string.html...
s ='hello word'print(s[0:5])# helloprint(s[0:-5])# hello 通过Python默认提供的len()函数获取字符串的长度,一个中文字符和一个英文字符的长度都记为1。 print(len(s))# 10 2.4 程序的语句元素 2.4.1 表达式 产生或计算新数据值的代码片段称为表达式。类似于数学中的公式,一般由数据和操作符构成。
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。 调用其方法的字符串被插入到每个给定字符串之间。
