此外,在第二版中,我采用了 Python 3.6 引入的f-string语法,它比旧的字符串格式化表示法(str.format()方法和%运算符)更具可读性,通常也更方便。 提示 仍然使用my_fmt.format()的一个原因是,当my_fmt的定义必须在代码中与格式化操作需要发生的地方不同的位置时。例如,当my_fmt有多行并且最好在常量中定义时...

This is a string with a single quote: '. 1. 使用转义序列的方法相对灵活,但当我们需要在一个字符串中插入多个引号时,代码可能变得冗长和难以阅读。 5. 使用格式化字符串 在Python 3.6及更高版本中,我们可以使用格式化字符串来插入引号。格式化字符串是一个以字母f开头的字符串,其中用花括号{}包围的表达式会...
string 对象的 split() 方法只适应于非常简单的字符串分割情形,它并不允许有多个分隔符或者是分隔符周围不确定的空格。当你需要更加灵活的切割字符串的时候,最好使用re.split()方法: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 >>>line='asdf fjdk; afed, fjek,asdf, foo'>>>importre>>>re.spli...
# 单引号创建字符串 string_with_single_quotes = 'Hello, Python!' # 双引号创建字符串 string_with_double_quotes = "Hello, Python!" 使用双引号可以在字符串中包含单引号,而不需要转义它们,反之亦然。 # 在双引号字符串中使用单引号 quote_in_string = "Python's syntax is clear." # 在单引号字符...
