>>> type(string.ascii_letters) <class 'str'> 学习笔记: 学习了一遍str、string,发现string几乎很难用到,字符串类型的大部分功能都在str类型中,除了Template类的使用,当然,这个也可以使用str本身的格式化功能实现,当然,Template会更便捷——语法相对来说较为简单。 关于Formatter类,string模块官文说它和str.format...
Astringis a Python data type that’s used to represent a piece of text. It’s written between quotes, either double quotes or single quotes and can be as short as zero characters, or empty string, or as long as you wish. Strings can beconcatenatedto build longer strings using the plus...
Python strings can be created with single quotes, double quotes, or triple quotes. When we use triple quotes, strings can span several lines without using the escape character. string_literals.py #!/usr/bin/python # string_literals.py a = "proximity alert" b = 'evacuation' c = """ req...
Strings in python are surrounded by either single quotation marks, or double quotation marks. 'hello'is the same as"hello". You can display a string literal with theprint()function: Example print("Hello") print('Hello') Try it Yourself » ...
方法/步骤 1 Python（特指Python 3）中包含字符串，字符串的类型为str，字符串是Unicode码点（Unicode code codepoint）的序列，属于不可变类型。字符串有三种写法：单引号（Single quotes）、双引号（Double quotes）、三引号（Triple quoted）。单双引号可以互相嵌套，三引号可以嵌套单双引号，使得字符串扩展为多行...

Python 也提供了可以通过几种不同方式表示的字符串。它们可以用单引号 ('...') 或双引号 ("...") 标识。\可以用来转义引号: >>>'spam eggs'#single quotes'spam eggs'>>>'doesn\'t'#use \' to escape the single quote..."doesn't">>>"doesn't"#...or use double quotes instead"doesn't"...
Strings are specified using single quotes①or double quotes②, as shown in the following code example. If a string contains a single quote, we mustbackslash-escape the quote③so Python knows a literal quote character is intended, or else put the string in double quotes②. Otherwise, the quot...
