2.python3.6加入的新格式化方案:f-strings 定义一个变量。 字符串前加f符号。 需要格式化的位置使用{变量名}。 #coding:utf-8 info='mynameis%s,myageis%s' name_01='小编' age_01=10 name_02='dewei' age_02=33 print(info%(name_01,age_01)) print(info%(
F-String was introduced in Python 3.6, and is now the preferred way of formatting strings.To specify a string as an f-string, simply put an f in front of the string literal, and add curly brackets {} as placeholders for variables and other operations....
f-Strings:一种改进版格式化方式 Python 3.6 引入了新的字符串格式化方式,这种方式来自于 Eric V. Smith 在2015 年 8 月提出的方案,具体可以参考PEP 498。 f-strings 也称作“格式化的字符串字面量”,它是一个带有 f 前缀的字符串,通过大括号嵌入所需的 Python 表达式,这些表达式的具体值是在运行时确定的,背...
为了进一步简化格式化方法,Eric Smith 在2015年提交了 PEP 498 -- Literal String Interpolation 提案。Python 3.6 引入了新的字符串格式化方式 f-strings,字符串开头加上一个字母 f ,与其它格式化方式相比,不仅简洁明了,可读性更好,更不容易出错,而且运行效率也更高 name='小伍哥' f'Hello,{name}' 'Hello,小伍...
f-strings 是指以f或F开头的字符串,其中以{}包含的表达式会进行值替换。 下面从多个方面看下 f-strings 的使用方法,看完后,我相信你会对「人生苦短,我用 Python」有更深地赞同~ 3.1 f-Strings 使用方法 代码语言:javascript 代码运行次数:0 运行
Single quotes and double quotes can both be used to declare strings in Python. You can even use triple-double quotes! Learn when to use each in this lesson as well as variable substitution in strings. foo ='What is up'foo='What\'s up'foo="What's up"foo="""what's up ...
Format strings contain “replacement fields” surrounded by curly braces {}. Anything that is not contained in braces is considered literal text, which is copied unchanged to the output. If you need to include a brace character in the literal text, it can be escaped by doubling: {{ and }...
This method is known as Literal String Interpolation or f-strings. It makes the string interpolation simpler by embedding the Python expressions inside string constants. It works by prefixing the string either withforF. The string can be formatted in the same way as the str.format() method. ...
1. in python3 use dict to formate strings: >>>print(“%(a)s” % {'a’:'b’}) b >>>a = ‘b’ >>>print(“%(a)s” % locals()) b 2. in Python 2.6 on up you can use the new format() method on strings: >>>'{a}'.format(a = ‘spam’) ...
1.引言 Python提供了几种方法来格式化输出，在本篇技术博客中，我们一起来看看Python格式化输出的技术和应用。①首先介绍字符串插值（f-strings）和str.format()方法来将变量值插入到字符串中，例如print('My name is %s and I am %d years old.' % (name, age))；②其次介绍了如何使用格式说明符来控制变量...
