f-string是Python 3.6引入的新特性,它允许在字符串中直接嵌入表达式,使得字符串的格式化变得更加简洁和方便。 # 定义一个变量name="Alice"# 使用f-string定义一个多行字符串,并插入变量multiline_f_string=f""" Hello,{name}! This is a multiline f-string. """# 打印多行f-stringprint(multiline_f_str...

过去的版本中,如果定义的f-string是单行字符串,那么大括号里面的表达式也必须写在一行内。现在这个限制也没了,只要符合语法就可以。例如: x,y=1,2print(f"""{x}.This is amultiline f-string.{y}.It can contain any text.另外:表达式可以换行书写:{x+y**3}""") 输出: 1.This is a multiline f...
The expressions that are extracted from the string are evaluated in the context where the f-string appeared. This means the expression has full access to local and global variables. Any valid Python expression can be used, including function and method calls. 翻译如下: 从字符串中提取的表达式在f...
