Python 2 中的格式化字符串文字 [英] Formatted String Literals in Python 2

问题描述

在 Python 2.7 中编写模块时，我需要一种方法

While writing a module in Python 2.7 I had the need of a way for doing

name = "Rodrigo"
age = 34
print f"Hello {name}, your age is {age}".format()

虽然我知道我可以做到:

although I know I could just do:

print "Hello {name}, your age is {age}".format(name=name, age=age)

format() 将在变量 name 和 age 的范围内查找，将它们转换为字符串(如果可能)并粘贴到消息.我发现这已经在 Python 3.6+ 中实现，称为 Formatted String文字.所以，我想知道(在谷歌上找不到)是否有人已经为 Python 2.7 开发了类似的方法

format() would look in the scope for variables name and age, cast them to a string (if possible) and paste into the message. I've found that this is already implemented in Python 3.6+, called Formatted String Literals. So, I was wondering (couldn't find it googling) if anyone has made an approach to something similar for Python 2.7

推荐答案

你可以通过结合内置的 locals 函数和 来尝试 hackish 的做事方式>format 字符串上的方法:

You can try the hackish way of doing things by combining the builtin locals function and the format method on the string:

foo = "asd"
bar = "ghi"

print("{foo} and {bar}".format(**locals())
